And God help you if you're uncut. Either you make a habit out of making sure your foreskin is well clear of the urethra every time you are about to take a piss (even if you're groggy as hell from having woken up at 1 in the morning and you want nothing more than to get your business over with and go back to bed), or get used to randomly having your jet spray at a ~90 degree angle from the direction you were aiming.
