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 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 the married men. ONE for January, ONE for February, ONE for March....etc."

Then, the little boy notices a full case of condoms at the end of the aisle. "Who would buy a whole case of condoms?" the now wide-eyed little boy questioned his dad. The couple standing just behind the dad perked up and beating the little boy's dad to an answer exclaimed, "SWINGERS"!
