Teenager's Condom Purchase

A teenage boy has a hot date one evening, so he decides to buy some condoms. He goes into the pharmacy and sees that there are 3, 9, and 12 packs of condoms. He talks to the pharmacists and says his date that night is really hot, so he decides to go with the 12 pack.

That evening, he eats dinner with his date and her family, and they ask him to say grace. He proceeds to do so and then continues to keep his head down and prays.

After a while, his date says, "I didn't know you were such a religious person."

He replies, "I didn't know your dad was a pharmacist!"
