I've seen this before, but I really needed a laugh today. You probably can't read the type, but Chuckie himself designed these trousers. They have a "special hidden gusset" so that the wearer has more freedom of movement. For research purposes only, I examined his crotch very closely and let me tell you, I can see the specialness.
What a dork.
