6. Phill Lewis, who plays Hooch ("Hooch is crazy!"), really did kill someone (while driving drunk), and served time in prison.
7. The gag where Dr. Cox (John C. McGinley) calls J.D. by girls' names comes from real life. McGinley actually does it to his buddy, John Cusack.
8. The episode "My Fault" (Season 3) is an homage to the film The Sixth Sense.
9. In the episode, Ben — the brother of Dr. Cox's wife, Jordan — always has his camera handy. It's only at the end, when Cox learns that Ben is dead, that his camera is gone.

12. Did you know that John C. McGinley also appeared in Wall Street and Platoon?
13. At the beginning of the series, Colonel Doctor, Snoop Dogg Resident, and Dr. Beardface were only meant to be extras. But the cast and crew could never remember the characters' names, and when their set nicknames stuck, they were incorporated into the show.
14. Sacred Heart was actually a real hospital — the North Hollywood Medical Center in Los Angeles.

22. In the Spanish-language version of the show, Carla speaks Italian as a second language instead of Spanish.

24. Ted's a cappella band, "The Worthless Peons," actually exists. The real group is called "The Blanks."
25. J.D.'s father was supposed to be a regular on the series. Unfortunately, the character died after John Ritter died in 2003.
26. You may have recognized the Janitor's father from Full Metal Jacket. Ronald Lee Ermey played Gunnery Sergeant Hartman in that film.
27. Dr. Cox's infamous nose flick was done in homage to the classic film The Sting, starring Paul Newman and Robert Redford.
28. Ever wonder what Turk and Carla's daughter Isabella ("Izzy") looks like now?
