A man goes to his doctor and says. "Doc, I have a problem. My girlfriend is sleeping over this Friday, my ex-wife is sleeping over this Saturday and my wife is coming home Sunday. I need 3 Viagra pills to satisfy all 3 of them.
The doctor says "You know 3 Viagra pills 3 nights in a row is pretty dangerous for a man of your age. I will give them to you on the condition that you return to my office on Monday so that I can check you out."
The man says "You have a deal Doc."
Monday morning the man returns with his arm in a sling.
The doctor says "What happened"?
The man answered "Nobody Showed UP!"
