Above a urinal at the place I work. "Don`t look up here, The jokes in your hand"

A maintenance company posted a sign above a row of urinals:

"Our aim is to keep this place clean - Yours will help! "

I saw this one above a urinal one time;
If your hose is too short,or your pump is too weak;stand real close,or you'll piss on your feet. Sounds like pretty good advice to me.
