Joe and girlfriend were walking over a bridge. Joe was caught short and peed through the railings, watching the lovely curve the pee made right down to the river
GF: I would love to try that
Joe: Hop up on the parapet and stick your ass out. Don't worry I will hold on to your arms
GF hops up, sticks her ass out and looks over her shoulder
GF: Hey, I'm going to piss right down into that canoe
Joe:That's no canoe, that's just your reflection in the water...boom boom
