A girl asks her boyfriend to come over Friday night and have dinner with her parents. Since this is such a big event, the girl announces to the boyfriend that after dinner she would like to go out and have sex for the first time as well.
Well, the boy is ecstatic, but he has never had sex before, so he takes a trip to the pharmacist to get some condoms. The pharmacist helps the boy for about an hour. 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, it being his first time and all.
That night, the boy shows up at the girl's parents' house and meets his girlfriend at the door. "Oh I am so excited for you to meet my parents. Come on in! The boy goes in and is taken to the dinner table takes his seat and shortly after her parents follow and take their seats. The boy quickly offers to say grace and bows his head. A minute passes and the boy is still in deep prayer with his head down. 10 minutes pass and he is still quietly praying. Finally after 20 minutes, the girl leans over to the boy, whose head is still bowed and whispers to her boyfriend, "I had no idea that you were this religious."
The boy turns and whispers back, "I had no idea your father was a pharmacist....."
