David Krumholtz played a psychotic young man in an episode of ER in which he attacked people because he thought that someone wanted to take his internal organs. In this episode, Larry recounts a recurring dream of someone wanting to take his internal organs, and at the end, Charlie is reluctant to sign a donor card because he wants to "hang on to his internal organs." Lots of "internal organs" references.
Charlie's birthday, according to his driver's license, is September 5, 1975.
First episode to open without the usual visual montage nor the voiceover.
