At open mic at Wiseguys, I mostly worked on arranging material. Except for one new joke, I was using older material, but playing around with tightening up bits and seeing where it all feels best. I need to do this a bit more often at some of the open mics that let me have longer than three minutes.
It's definitely an art! I like experimenting and just generally practicing being on stage. I'm told I'm going to hate these videos in a while. We'll see... It's good for other beginners to see how long it really takes to get good at comedy, I think.
Also, the comic before me spent her 3 minutes saying the word "pussy" 15 times, so I had to comment on it right up front.
