Why boxes of 3, 6 and 12?

[DEEJAYKEG]

A man walks into Boots with his 8-year old son.
They happen to walk by the condom display, and the boy asks, "What are
these, Dad?

To which the man matter-of-factly replies, "Those are called Condoms son.
Men use them to have safe sex."

"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 college men," 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 sigh and a tear in his eye, the dad replied.

"Those are for married men, son. One for January, one for February, one for
March......."
