I don't really know. I think the first test is when you're very little and you fart, and you laugh at it and so do your friends and family. I knew before I was funny I was very annoying so I have that covered. I think it was because I was not very good in school I used humor as a defense mechanism. When I started doing plays and stuff at school I decided that I was going to keep doing it until someone tells me to stop and get a real job.
