A young man goes into a drug store to buy condoms. The pharmacist says the
condoms come in packs of three, nine or 12 and asks which the young man
wants.

"Well", he said, "I've been seeing this girl for a while and she's really
hot. I want the condoms because I think tonight's THE night. We're having
dinner with her parents, and then we're going out. Once she's had me, she'll
want me all the time, so you'd better give me the 12-pack."

The young man makes his purchase and leaves. Later that evening, he sits
down to dinner with his girlfriend and her parents. He asks if he might give
the blessing, and they agree. He begins the prayer, but continues praying
for several minutes.

The girl leans over and says, "You never told me that you were such a
religious person."

He leans over to her and says, "You never told me that your father is a
pharmacist!"
