I'm gonna have to go with "Laundry Day". While I loved "Pretty Fly for a Rabbi", I have to admit I would have preferred Al expanded on the laundry theme and done a full-blown version of "Laundry Day" for his RWS Offspring parody. I mean, laundry is a funny thing to sing about! Novelty songs with Jewish themes are sort of a dime a dozen (Allen Sherman made a living off of them! "Rabbi" was probably Al's nod to the original Master of Parodies, in a way).
