Bettie: Why are you here, Carmen?
Carmen: I paint nude ladies and skeletons. And sometimes derelicts with a bottle of booze in their hands. I'm a pervert and a ne'er-do-well, can't you tell?
Otis: Kids at school used to say, "Where's your mother?" What was I supposed to say? "She's taking retreat with a maniac painter and other assorted psychos"?
Lilly: I used to say mine was on tour with a rock band.
This episode shares the name with episode 5-21: Committed of CSI. Also the two cases share some similar aspects to them; there is a murder in a mental hospital and all of the suspects are mental patients. Coincidentally, Robin Weigert (Det. Anna Mayes) guest starred on both episodes.
Carmen discusses Michelangelo's marble statue David in art class as an example of the idealized human form. Sculpted during 1501-1504, it is widely considered a masterpiece of Renaissance sculpture.
