At the Drug Store

A man walks into a drug store with his 8-year old son. They happen to walk by the condom display, and the boy asks:

- What's 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 boys 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, the dad replied:

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