My mom was my English teacher in high school. So to be able to bend the rules and be the class clown and get to take on my religion, my mom, and my town all at the same time was glorious. I think the desire to be funny was a mixture of wanting to be liked but also wanting to throw your elbows a bit. If you're cracking a joke in school, it's sort of anti-authority, but it's in the nicest, "Please like me!" way.
