Last night I laughed more at Gary's jokes than John's or Alonzo's, but I voted on last night's performance and previous performances. I really couldn't choose between Gary and John, so I used two different e-mail addresses and voted three times for each of them

(Gotta love loopholes

...I thought they were monitoring based on IP addresses or something else)
Alonzo has never really impressed me. I think there was one time that I thought he was great, but the rest of the time he was only "meh"
I agree with what MysticCat said about Gary picking up on the little things and making them funny. I think it's that type of "sarcastic" wit that makes me laugh the most
