A man goes into the pharmacy with his 10 year old son. They happen to walk by the condom display, and the boy asks, "What are these, Dad?"
The man doesn't believe in hiding things from his son, and thinks he is old enough to learn about such things, so he says, "Those are called condoms, son. Men use them have safe sex, and for birth control."
"Oh I see" replied the boy pensively. "Yes, I've heard of that in health class at school".
He looks over the display and picks up a package of 3 and asks, "Why are there 3 in this package?"
The dad replies, "Those are for high school boys. One for Friday, one for Saturday, and one for Sunday".
"Cool!" says the boy. He notices a 6-pack and asks, "Then who are these for?"
"Those are for university guys" the dad answers. "TWO for Friday, TWO for Saturday, and TWO for Sunday."
"WOW!" exclaimed the boy. "Then who uses THESE?" he asks, picking up a 12-pack.
With a sad sigh, the dad replied, "Those are for married men. One for January, one for February, and one for March..."
