3 close friends from Utah were off to college. One heading for Harvard. One to MIT. One to Texas A&M. Many beers were sunk, promises to keep in touch - the usual last night at home thing. And a promise that they would all meet up in a year.
The year passes, and there they are in the same bar again. Laughing and joking, as if they'd never been apart. Catching up, having fun. The beer, as is it's wont, caught up with them. All three made a beeline for the gents. Three urinals, so no problem. They have their pee, then the Harvard and MIT guy head to the sinks to wash their hands. The A&M guy shakes, zips, and starts walking out the door.
"Here, Don! In Harvard we are expected to wash our hands after going to the toilet!" shouts the Harvard guy.
"In Texas we are taught not to piss on them in the first place."
