Actor Christopher Mintz (who probably hates everyone yelling "Hey McLovin!") was in Superbad, and that scored him a role in Role Models (a very disappointing comedy).
I just saw him in the movie Kick-Ass (you can read my full review on SanDiego.com).
Well, he was on Jimmy Kimmel to promote it. He talked about being at a restaurant and trying to impress his friends by sending a bottle of champagne to some older women. They sent it back and he felt foolish. As Kimmel asked why he thought older women would care about him he replied, "You should see how many of them want me to autograph their breasts. I've had at least four. Sometimes they'll say 'My husband is right there. He really wants you to do it.' I tell them Sharpies are permanent ink, and are they sure? I've stopped doing it now though, even though they try insisting."
