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 familypack because he thinks he will be rather busy, it being his first time and all.

That night, the boy shows up at the girls parents house and meets his girlfriend at the door. "Oh I'm so excited for you to meet my parents, come on in!"

The boy goes 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, and the boy is still deep in prayer, with his head down. Four minutes pass, and still no movement  from the boy.  Finally, after nearly ten minutes with his head down, the girlfriend finally leans over and whispers to the boyfriend, "I had no idea you were this religious."

The boy turns, and whispers back, "I had no idea your father was a pharmacist."
