What the hell is a Goatse photo?

Internet amateur. :(

If Jamesman were here, he'd show you even better pictures. :(

Crediblity. Showing your sources is one of the most fundamental rules of writing persuasively.

Don't make Vince tell his sources. First of all, it would take away the one thing in the world he has aside from his "sorta girlfriend", which would be his knowing he has knowledge that everyone else lacks. If he gives his sources, then we will all know what Vince is talking about, and then he won't think he seems so smart. Secondly, he really looks like a complete dick when he doesn't, and that is all anyone really cares about.
