Part of the fun of watching The Simpsons is trying to guess who the guest voice is each week. This episode had five guest voices packed into the episode, some of which were easier to guess since the actors were playing themselves, of course: Steven Sondheim, Meg Ryan, Peter Bogdanavich, Andy Dick and James Patterson.
