Not the joke itself, but the fact he even made the joke. Or maybe he's just a psycho. I don't get the joke but would like to get in on it. OPs link was good but I agree that yours is the better joke. See More Glory Hole Videos!

Yes, he has, true. She sucks him, but he pops his load while she is giving him a handjob. Why is this joke funny? Am I crazy or was that really not that much of a funny line? Once he knew where the line was it allowed him to cross it appropriately. They have both presented TV shows and rarely laugh at other people's jokes.
