A guy has been pressuring his girlfriend for sex. Finally she says, "Come over for dinner. It might be your lucky night."
Excited, he goes to the pharmacy to pick up some condoms. He waits for everyone to leave the story and finally goes up to buy them. "You buy these a lot?" the pharmacist asks.
"No," he replies, "Just hoping to get lucky tonight."
When the boy finally gets to his girlfriend's house that night, her father says, "At our house, the guest always gets to pronounce grace."
The boy quickly bows his head and recites prayers from religions around the world. After dinner his girlfriends tells him, "I had no idea you were so religious."
The boy replies, "Yeah, well I didn't know you're dad was the town pharmacist."
