I think it's because he's too self aware in this clip. During the show it almost seems like he doesn't expect whats going to happen next. Also having a Hannibal Buress playing the straight man doesn't hurt either.
Still, I'll 5 because he kept it short and I was surprised how many old ladies laughed at his dick.
Ok, now Eric makes sense to me. Also this is only the second time I've seen him, cause I live in a hole, but this was funny. Also Arsenio is looking great. Woo Woo Woo!
