Two teenage virgins have been dating for a few months.
One day the girl calls up her boyfriend.

"I think I'm ready to go to the next level," she purrs. "I want you to come over tonight for dinner. My parents want to meet you, and then they're going out."

Then with her most seductive whisper she adds: "We'll have the house all to ourselves."

The boy nearly faints from excitement. He immediately rushes out to the pharmacy to get prepared. When he arrives, he’s utterly confused by so many different brands of condoms. He doesn’t know what to do.

Sensing the boy’s anxiety, the pharmacist walks over and begins to offer some help. He patiently explains to the boy all the different types of condoms, their pros and cons, and how to use them. Eternally grateful, the boy thanks him profusely for the advice and makes his purchase.

That night, as they gather around the dinner table, the girl turns to her boyfriend and asks him to lead the family in saying Grace. He clenches his eyes shut, drops his head and begins to pray reverently. His prayer goes on and on for minutes with ever increasing intensity until the family begins to get worried. The girl gently taps him and whispers, "I never knew you were so religious."

He says, "I never knew your father was a pharmacist."
