A father and his eight year old son where walking down the aisle in a drug store when they happened to pass by the condoms.
The boy asked, “What are these, Dad?”
To which the father replied, “Those are called condoms, son. Men use them to have safe sex.”
“Oh I see,” replied the boy pensively. He picked up a package of 3 and asked, “Why are there 3 in this package?”
The dad replied, “Those are for high-school boys. One for Friday, one for Saturday and one for Sunday.”
The boy noticed a 6-pack and asked “Then who are these for?”
“Those are for college men”, the dad answered, “Two for Friday, two for Saturday, and two for Sunday.”
Then who uses these?” he asked while picking up a 12-pack.
With a sigh, the dad replied, “Those are for the married men, One for January, one for February, one for March…”
