A man and a blonde meet in an elevator.
“Where are you heading today?” the man asks.
“I’m going down to give blood.”
“How much do you get paid for giving blood?”
“About $20.” “Wow,” says the man, “I’m going up to donate s**p*rm, and the s**p*rm bank pays $100.”
The woman angrily gets off the elevator.
The next day, the man and woman meet in the elevator again.
“Fancy meeting you again. Where you off to today?”
“S**p*rm bank,” she says with her mouth full.
