King Chicken: Relax; you've got the best seat in the house!
Duckman: Well I appreciate the compliment, but I don't swing that way.
Iggy Catalpa: So this medical caregiver of indeterminate gender--because nurses can be male or female--says to his or her disabled--or should I say, differently-abled--patient, 'Why do you have a penguin on your head? They're endangered!' Haaaa!
Music by Frank Zappa included in this episode:
Theme from Lumpy Gravy
This is the last episode to feature Frank Zappa's music.
Iggy probably represents Woody Allen (He has the basic look of Allen, but Allen is not exactly a "clean" comedian), and the Senator's suggestion of using white-out of the constitution of the United States Of America is probably a refferance to the P.M.R.C. court hearings, in which Frank Zappa was a witness to (Zappa's music also appears during this episode, and much of the first season's episodes. The Pilot, "I, Duckman" was dedicated to FZ.)
The comedian Roulette is a caricature of Andrew "Dice" Clay, in both appearance and humor.
Choking the Chicken:
The title of this episode is a parody of the euphemism choking the chicken (i.e. masturbating).
