a kid is buying condoms at a pharmacy. the pharmacist helps him out and the kid goes "i'm hoping to score some tonight, visiting perents...blah blah blah."

then at dinner the kid says prayer for a long time and the girlfriend says "i didn't know you were so religous/have so much faith"

the kid replies with "i didn't know your dad was a pharmacist!"

or something along those lines....
