Someone actually gets it! Seth’s performance was his usual, just toward a broader audience, most of whom aren’t used to his kind of humor. On top of that, he knew he was playing to that audience. He said he didn’t want to do it again, and his boobs song was part of his way of making sure they didn’t bring him back. He’s an awesome person who knows how to laugh at anything, put a twist on it that isn’t insulting, just funny. If people could get that through their heads, they’d learn how funny it is that they are offended by his work at all.
