I could never understand that. If you're basically the greatest, or one of the greatest, why would you even want people writing for you? Maybe they wrote hooks for Nas
They hire a bunch of writers and they submit jokes. The star decides if he wants to use them or does he want to modify them. It's not about how great you are, those comedy shows are put together by the comedian and a team of writers that he trusts. Jay Leno does jokes every night but he doesn't write all of those jokes either. He has a team of writers. When Kevin Hart did BET and he would come out and tell his jokes, he had writers help him come up with the best jokes possible. Just because you think something is funny doesn't mean everyone else will. That's where the writers come in to help.
