Greenzo-- Schwimmer was hysterical and the subplot of Kenneth's party. "What's a Tracy Jordan Jam? 'Hiyooooo'...."
The aftermath of the party had me in tears and still makes me laugh. The evening took a bad left turn, Baldwin's disheveled hair,Liz puking and eating the cupcake, Cherie punching Jack, the Harlem Globetrotter, Tracy stealing a sink...it was gold. That scene alone had it as my favorite episode.

haha, that episode is great. It's hard for me to pick a favorite, so it's probably a 4-way tie for Cleveland, Black Tie, Somebody to Love, Sandwich Day.

Gotta be 'Hard Ball' (s1e15) for me - the worm and the crab, taking it to the back of middle school and getting it pregnant, yo burnt, shut it down...so many classic moments.
