If I met God and had the chance to ask him/her/it one question I'd ask, "what were you smoking when you designed the wang!" Everyone things peeing standing up is the greatest thing ever, but it's not. It's a real pain in the ass some times. The wang is not a reliable instrument. You're trying to pee into a toilet and that thing is all over sometimes. Specially on a hot day when you got some stickage or bendage you're all over.
Don't get me wrong, it's not THAT hard to aim the thing, but it's totally unreliable and inconsistent.
