A young man in a drug store asks the pharmacist for condoms. "They
come in packets of 3, 6 or 12," responds the pharmacist, "How many do
you need?"
"Well" muses the young man, "I've known this wonderful girl for 7
months. Tonight I'm meeting her parents for the first time, then we're
off to an all-night party.
So I think tonight's the night. And, once she gets it, I know she'll
want more. Better give me a dozen!" Having made his purchase, the
fellow drives home, dresses for dinner and arrives at his girlfriend's
house. At dinner, he is asked to offer the blessing. He prays - and
prays - and prays - and prays. Finally, his girlfriend leans over and
says "You never told me you were so religious!" He answered her, "You
never told me that your father was a pharmacist!"
