Carla's threat in Spanish that she tells J.D. about Elliot is for Elliot "to watch her little behind, because if she doesn't, I am going to kick all the blonde dye off her head."
This is one of the only episodes you see the front of the hospital.
The character of Will Forte, played by John Ducey, is named after Will Forte, who worked with the show's creator Bill Lawrence on Clone High (2002).
This is the only episode in which you can actually see the characters in the small hallway by the reception and waiting room. J.D. and Will (his patient that smokes) use this exit. In all other episodes, the camera faces the opening only, without showing them in the hallway.
This is the first time that featured the "Sacred Heart Hospital" logo.
