A young man is browsing the condom section of a drug store when the Pharmacist approaches him and asks if he can be of assistance.
"I'm not sure which condoms to use. I'm pretty sure that my girlfriend and I are going to sleep together tonight for the first time, and I want to get it right the first time."
The Pharmacist tells the young man everything he needs to know about safe sex and all about the different kinds of condoms. Then he asks the young man what size he'll need; the 3-pack, the 10-pack, or the family pack.
"Definitely the family pack! She and I are going to be pretty busy tonight!"
That night, the young man visits his girlfriend at her parent's house, having been invited earlier for dinner. He takes his place at the dinner table and asks if he could say grace. The girl's mother agrees, and the young man starts to pray silently.
After a minute, the young man is still praying. After 5 minutes he's still praying.
Curious, his girlfriend nudges him, and whispers to him, "I had no idea you were so religious!"
The young man, his head still bowed, replies, "I had no idea your dad was a pharmacist!"
