Mr. Show is some really top notch stuff. I'm sure if all of the actors weren't so hideous they'd be getting more roles than Jonah Hill (Did you see what I did there? He's a bit hefty so he's got fat rolls. He's also been in quite a few hit movies recently. Ask your mother about getting roles, they should call that ho a bakery on account of all the rolls she's got.).
I always try to do something with the thought in mind, "Would I find this funny if I was watching it?". Doing a monologue just running around a casting director's office shouting at people would make my day. This would be almost as much fun to do as "The Audition". Its not easy being a failed actor, but at least I dont work at a gas station.
