I am getting really tired of posting this to people who have never watched the show.
Muhammad. Not rooting in a pig sty, but rather, standing next to Jesus as one of the "Super Best Friends" - a takeoff on the SuperFriends cartoon of my childhood. They did this a few seasons ago, before showing Muhamad in a cartoon was considered some kind of litmus test for whether a comedian had "guts".
You want to portray him in a pig sty? Think that'd be funny? Get your own show. As for Matt and Trey, they have their own way of looking at things, and have a pretty good track record for finding what's funny about people. They'd probably find more humor in YOU daring them to draw Muhammad than any drawing of Muhammad ever would have.
At least I think you're pretty funny.
