Viewer Mail #1 rules. I mean, Goldberg is in it, how could it NOT rule?
I kinda liked When You Wish Upon a Weinstein. The first time I watched it I thought it was really lame, but upon second and third viewings I caught some funny stuff, like the aforementioned "looking for the keys" and the talking clouds. His "I Need a Jew" song is kinda catchy too.
To Live and Die in Dixie is also a great episode. "OH GOD! IT'S EVERYWHERE! IT'S IN MY RACOON WOUNDS!"
