Personally, I thought the best comics last night were John, Tammy, and Dave.
I've always loved John's comedy, and part of that reason is he keeps bringing new material every time. I liked the playstation vs. atari and finding cheat codes jokes.
I haven't liked Tammy much in the past, but the Scarlet O'Hara bridesmaid's dress had me rolling. I love when she said she'd wear it again to the birth and graduation...I think that took an old joke and made it new.
Dave was funny, AND funny looking! Kateshort was right about Keith Richards...I was thinking Bon Jovi, myself.

The cows and cars jokes, however, were great.
Alonzo and Rich were also okay. Ralphie will get a lot of sympathy votes (although if he had performed under normal circumstances, I'm pretty sure it would have been a good set). The others weren't very memorable.
I don't really understand the rules of the show though...I know the house/comic with the most votes greats 50 tho., but how many people get kicked every week? How does elimination work?
