leak of faith
when a guy runs into a bathroom about to piss himself, but its pitch black inside so he pulls it out and takes a piss hoping that he is landing in the urinal and/or toilet minimally the sink over the floor.

special note: every time a blind man takes a pee he is taking a leak of faith
Chris ran into the bathroom and shut the door, reached for the light switch but it was out after feeling his way around the room he assumed he was standing in front of the toilet, and pissed only to find that he was pissing in some other guys lap, he took a leak of faith and fate was not kind to either gentlemen!
