Trivia

This is one of the only two episodes in which the guest star uses a pseudonym instead of their real name (the other being "Stark Raving Dad").
Dustin Hoffman's pseudonym 'Sam Etic' was chosen as reference to his character being Jewish or "Semitic".
In one particular scene, ~~Baby Maggie~~ whimpers a little, Nancy Cartwright was asked to play Maggie and she accepted but she spotted her husband (they are divorced now) and her daughter (who was a baby at the time) walk in the studio. She asked one of the directors if her baby could do the little whimpers for Maggie. The director said yes and Nancy Cartwright's daughter actually made the whimpers of little Maggie.
