Joke, do not read if you are a young child!

Bloke desperate for loo in Chicago Hospital. Is told by nurse to use ladies but NOT to touch any buttons on wall. Inside there are 4 buttons marked WW, WA, PP AND ATR. Curious, he pressed WW and was gently sprayed with warm water. He then pressed WA and warm air dried him. PP produced a power puff so he decided to finish with ATR. He woke up in hospital bed and same nurse says ???ATR means Automatic Tampon Remover??????. Your c.o.c.k's under you???re pillow!
