Seen Judah Friedlander (30 Rock) perform a bunch of times in the past couple of months and I really dig his act. It's all one joke: He's a fat slob who claims to be world champion...of everything.
This one joke is stretched as far as it can go. Sex, sports, whatever, he's the best. He's ready for anywhere the crowd takes it. You play softball? He plays hardball. And yesterday he bunted a home run. And before that he pitched a perfect game, from left field. Etc. It's all got an old-school, Rickles-ish schtick feel to it.
He sells it by not selling it. He delivers it in a "I couldn't care less about all this" tone. He's turned not giving a shit into his whole act. (Nice performance work if you can get it.) Still, he's super quick with crowdwork and totally on point with his timing and delivery.
Pros to doing something like this: tight focus, easy hook for people to remember you, anyone can get it, etc. Cons: I wonder if it feels limiting to have your entire act be about one topic?
