isaac hayes
A huge, huge hypocrite. Of course, he's a scientologist. As Matt and Trey put it: "When we were making fun of other religions, he kept cashing in the checks, but when we made fun of his religion, he said he didn't approve of insulting people's religion" or something along those lines.
Isaac Hayes is a hypocritical ass. But hate him, not the character Chef. Or neither if you prefer.
