I'm never shaking another hand EVER! -foul language-
The next time you shake someone's hand, hi5, anything that requires you to touch someone else's hand at all, the next time you do this I want you to look down at that person's hand and know... not think, this isn't a guess, I want you to FUCKING KNOW!!! that they've used that hand at some point in their life to JACK-OFF!
Howie Mandel got it right, FML.
