Joke from The Negotiator
This reminds me of a joke from the movie The Negotiator.
A marine and a sailor are in the bathroom taking a piss. The marine goes to leave without washing up. The sailor says, "In the navy, they teach us to wash our hands." The marine turns to him and says, "In the marines, they teach us not to piss on our hands."
I should note though that I absolutely agree with Mr Chao on this issue. I remember many times being at the 5 and seeing guys just walk out of the men's room without washing their hands. Disgusting! I sure hope they're not going for dances after that! I do remember a few ladies who would make you use hand sanitizer before starting a dance. Smart girls!!
