I was Minnie Mouse for Halloween, every year when I was little. Then, I had the Cinderella nightgown, when I was really little, that I begged my mother to wear to school. I was also Snow White a lot.
I like trying jokes and seeing the response, and if I end up doing it in my act, it won't be 140 characters. Twitter is helpful that way to me. It's like a message in a bottle. But a lot of times I think I tweet the stuff I would like to say to teenage me.
Comics who grew up surviving their childhood by being able to be the first one to make the joke about their weight or their hairy arms - like me - whatever they're insecure about, whatever they're apologizing for, that becomes their strength.
