1. J.D.
   Chris
2. Eliot
   Perry

Turk's first name is Chris in the show. Turk appears in more episodes than almost any other character in the entire series. In fact, he only missed three episodes in season 8 and, along with John C. McGinley, was the only actor from the main cast to regularly appear in season 9.

1. Right Said Ted
   Ted and the Kats
2. The Right Stuff
   The Worthless Peons

Ted's singing group in the show went by a number of names, including Ted's Band, but the Worthless Peons may be the most memorable. In real life, Sam Lloyd, who played Ted, is actually a singer in an acapella group called the Blanks.

1. Ohio
   Delaware
2. Florida
   Canada

J.D. is supposed to be from a town called Trotwood, in Ohio. Weirdly enough, although we know that Sacred Heart is the name of the hospital where everyone works in the show, they never clarify what state or city the hospital is in.

1. They have a group hug.
   They eat cake.
2. They sing.
   They wear dress pants.

The Dorian family tradition of breaking bad news involves the eating of cake. In one episode, J.D.'s brother shows up with a cake, and J.D. immediately knows something is wrong. Unfortunately, their father had died.

1. The Todd
   No Regerts
2. DOC
   MOM

Todd Quinlan, better known as The Todd, had a tattoo that just said "DOC." On set, Robert Maschio, who played The Todd, would routinely prank Donald Faison by putting dog poop outside of his dressing room door.

1. Rover
   Dog
2. Sticks
   Rowdy

In a very technical way, Rowdy is the pet dog that J.D. and Turk have. It's technical since the dog isn't actually alive at any point in the show — it's stuffed. J.D. and Turk had bought him at a yard sale eight years prior.

1. "Achy Breaky Heart"
   "My Tuscaloosa Heart"
2. "Friends in Low Places"
   "Goodbye, Earl"

After hearing "My Tuscaloosa Heart" on a tape, Eliot is positive that Dr. Kelso is the singer, but he denies it. Because the song is about a woman named Bunny, it's somewhat ambiguous. Later we find out that Dr. Kelso calls his wife Bunny.

1. John Ritter
   Harry Anderson
2. John Laroquette
   John Goodman

John Ritter, most famous for his role on "Three's Company" back in the day, appeared on "Scrubs" as J.D.'s dad. It was one of the last roles Ritter played before his untimely death in 2003, outside of his own series "8 Simple Rules for Dating My Teenage Daughter."

1. James Daniel
   Jacob Dylan
2. John Dorian
   Joseph David

J.D.'s real name is John Michael Dorian. He's based on a real person, Dr. John Doris, who was a friend of the show's creator. Doris was also a medical adviser on the show, helping to keep the situations rooted in a bit of reality.

1. Glenn Matthews
   Neil Flynn
2. Paul Hooper
   Sam Davis

After many misdirections and jokes throughout the show's first 8 seasons, Janitor's name — Glenn Matthews — is finally revealed in the last episode of season 8, which was meant to be the show's finale. Surprisingly, the show did continue for another season.

1. Bill
   Jay
2. Tommy
   Doug

Putting one final joke on what seemed like a sincere moment, Janitor tells J.D. his name and points out that, in all their years together, J.D. had never asked what it was. Then someone else randomly walks by and calls Janitor "Tommy," to which he responds as though that's his name,

1. "The"
   "My"
2. "A"
   "Here"

Because almost every episode of the show is told from J.D.'s perspective and includes his inner monologue, the titles are named from his perspective as well. As a result, nearly every title starts with "My," such as "My First Step" and "My Journey."

1. Turk
   Eliot
2. Julie
   The Todd

Julie, played by Mandy Moore, had a relationship with J.D. for a while. Aside from buying half an acre of land together, they shared a love of pop culture, including "Harry Potter." In real life, Zach Braff and Mandy Moore were in a relationship for a while as well.

1. Ham Bone
   King Koopa
2. Master Blaster
   Chocolate Bear

Over the course of the series, Turk is probably given three or four dozen different nicknames, but one of the most often used is Chocolate Bear. At one point it even gets upgraded to Super Chocolate Bear.

1. Eliot
   Dr. Kelso
2. Carla
   J.D.

If you go back and watch season 1 again, you'll notice something weird about Janitor — he only interacts directly with J.D. The reason? Because the producers didn't know for sure if the show would succeed, they wrote Janitor as if he were just in J.D.s mind and didn't really exist. If the show had tanked, the season 1 finale would have revealed that Janitor was not real.

1. Life
   Clue
2. Monopoly
   Risk

J.D. carries a top hat from the game Monopoly around with him for good luck. When he shows it to Turk, Turk gets offended because J.D. compares it to Turk's religious beliefs. Turk asserts that a good luck charm doesn't compare to a religion.

1. "General Hospital"
   "Guiding Light"
2. "Passions"
   "Days of Our Lives"

Dr. Cox is pretty sharp with his tongue on the show, but he still loves to watch "Days of Our Lives." He's also a fan of movies starring Lee Marvin, the Detroit Red Wings, the Pittsburgh Steelers and Carla.

1. Dog names
   Girls' names
2. Gibberish names
   Food names

Dr. Cox has a bad habit of referring to J.D. by girls' names. One of his favorites seemed to be Carol, and there was at least one incident in which he had Eliot call J.D. "Betty" over the phone on his behalf.

1. J.D.
   Todd
2. Ted
   Janitor

Todd's kind of a creep at the best of times, so it's no surprise to learn he has a collection of banana hammock undies in his home. In a few episodes, actor Robert Maschio bravely wears one.

1. Master a new language
   Learn to fly
2. Climb a mountain
   Complete a triathlon

In the episode "My Day at the Races," J.D. runs a triathlon, something he promised to do before he turned 30. Since it's almost his birthday, he tries to do it with no training and no preparation. He doesn't even have a wetsuit for the swimming portion.

1. Elliot
   Carla
2. Turk
   Dr. Cox

Eliot is prone to a lot of irrational fears, and one of them is being spoken to while on the toilet. She only has one rule in her apartment: no one can speak or be spoken to while they're doing their business.

1. Carla
   Turk
2. Elliot
   Dr. Kelso

This one's a little tricky, as the eggs getting named aren't the breakfast kind. Elliot reveals that she names her eggs every month. When she mentions it to J.D. the name currently being used is Hailey. The previous month it was Cassie.

1. Starbucks
   Sacred Heap
2. Sugar Bear
   Sacred Fart

J.D. changes the name of the hospital on a banner to "Sacred Fart" as a prank to make himself feel better. During the same episode, he tries to run a triathlon in an effort to make himself feel a bit younger.

1. Foxes
   Squirrels
2. Skunks
   Fish

Janitor owns what is described as a squirrel army. There are apparently something in the neighborhood of 150 stuffed squirrels in his collection that he killed and stuffed himself. He speaks to the squirrels and even lets them vote on things.

1. Ted
   Dr. Cox
2. Dr. Kelso
   Janitor

In one of the show's best jokes, J.D. catches sight of Janitor in the movie "The Fugitive." In real life, Neil Flynn, who plays the character of Janitor, was in "The Fugitive," which is why the joke works so well. It's one of the only times you'll see a character from one show or movie referenced by a character in a different show or movie while still being entirety fictitious.

1. Dr. Kelso
   Dr. Cox
2. Dr. Beardface
   The Todd

Dr. Cox has a penchant for flicking his own nose, and it's intentional. The actor, John McGinley, included the gesture as a character trait in honor of the movie "The Sting." In that film, Robert Redford and Paul Newman did the nose flick gesture to indicate all was well.

1. Eagle
   Hawk
2. Chicken
   Pigeon

J.D. screams out "eagle" in a scene from season 1, and it immediately became a meme related to the show. It's probably one of the most popular quotes — Zach has said that people scream it at him all over the world. The best part is, he improvised the line.

1. Griffin
   Dragon
2. Unicorn
   Bigfoot

J.D. has a small obsession with unicorns throughout the show's run. When things start to really stress him out, he even has a toy unicorn named Justin that he goes to for advice and to help decide what he needs to do.

1. Flips an X-ray
   Reorders the cast
2. Changes the hospital name
   Replaces Elliot

There's an image of an X-ray in the opening credits of the show that the production team didn't realize was backward until someone pointed it out to them. When Elizabeth Banks shows up in season 5, her character flips the X-ray the right way and makes a joke about it.

1. Dog
   Cat
2. Squirrel
   Finch

Rowdy the stuffed dog was replaced by a second stuffed dog, named Steven. The original stuffed dog went missing because a crew member got fired and stuffed it into the ceiling to hide it as a bit of revenge. The crew couldn't find the same dog again, so Steven was brought in.

1. Elliot
   Laverne
2. Ted
   Doug

The writers of the show killed off the character of Laverne in a car crash because they thought the show was going to be canceled. When it came back, they brought actress Aloma Wright back as the character Shirley, who, of course, looks exactly like Laverne, but only J.D. notices.

1. "Ghost"
   "The Sixth Sense"
2. "The Notebook"
   "Old Yeller"

Often cited on lists and pop culture sites as the best episode of the series, "My Screw-Up" is an homage to "The Sixth Sense." The movie features the same twist as the film and offers up clues upon rewatching about what was happening.

1. Heather Graham
   Masi Oka
2. Sarah Lancaster
   All of the above

Only three actors were unable to return for the big (almost) series finale of the show. Both Masi Oka and Sarah Lancaster were forbidden to appear on the show because of NBC contracts. Heather Graham was unable to appear for other reasons.

1. James Brolin
   Martin Landau
2. Jack Lemmon
   R. Lee Ermey

R. Lee Ermey, maybe best known for his role in "Full Metal Jacket," played Janitor's father — or maybe he didn't. Janitor, known for lying a lot, at one point says the man was a cat trainer when he was younger and later says his father has been dead for years.

1. Peregrine Ferdinand Cox
   Periwinkle Blue Cox
2. Percival Ulysses Cox
   Persephone August Cox

Dr. Cox is known by the first name Perry in the show, but that's short for his full name, Percival Ulysses Cox. You can see why he has a habit of making jokes out of other people's names, being a little insecure about his own.
