Yeah do jokes that are about topics that people can relate to but conveyed in a creative way. like a comedian can say my ex was a bitch but if you just say that it isnt funny. You should analyze how the diffrent ways to go with it. Its also the delivery. You gotta get emotional with your voice. Monotone usually isnt funny.

start off by saying "i've never been on a stage before i hope i dont fuck up

plenty of dick jokes
plenty of them

I love accents and sexual jokes.
Racial jokes are cool too but don't offend your audience, just make some funny ones like:

Why do black people like basketball?

It involves Running, Shooting and Stealing.
