Please don't ever shake my hand.
And for those saying it's not that hard to not pee on your hands, you still have to touch your "lil soldier." If you can unzip, whip it out, aim, and then put it away without ever touching yourself then that is a skill I'd love to see. Errr, I mean I don't really want to see it, but you know what I'm saying

I don't care if you didn't pee on your hands, touching certain body parts always requires a hand washing in my book.
