A girl asks her boyfriend to come over Friday night to have dinner with her parents and then have sex for the first time together.
The boy is ecstatic, but he is a virgin, so he takes a trip to the pharmacy to get some condoms. The pharmacist helps the boy for about 30 minutes. He tells the boy everything there is to know about condoms and sex. At the register, the pharmacist asks the boy how many condoms he'd like to buy -- a 3-pack, 10-pack or family pack. The boy insists on the family pack because he thinks he will be rather busy.
That night, the boy shows up at the girls parents house and meets his girlfriend at the door. They go inside and is taken to the dinner table where the girl's parents are seated. The boy quickly offers to say grace and bows his head. A minute passes, then 10 minutes, and the boy is still deep in prayer. Finally, after 20 minutes with his head down, the girlfriend leans over and whispers to the boyfriend, "I had no idea you were this religious."
The boy whispers back, "I had no idea your father was a pharmacist!"
