“ Dad had this story. A Marine and a Navy guy walk into a bathroom together. They both take a piss, and then sailor goes to the sink. The Marine heads for the door, and the sailor says, Hey- in the Navy they teach us to wash up after we take a leak. And the Marine turns around and says, Yeah? Well, in the Marines they teach us not to piss on our hands. ”
