An old guy is standing in the isle at a pharmacy looking at a rack filled with condoms.....

After he had been there ten or fifeteen minutes the pharmacist came out and asked him if he needed any help?

The old guy says "Na, I am just wondering about the unusual way those things are packaged,,singles, three packs and dozens,,that seems odd to me."

The pharmacist says, "Oh, thats simple, the singles are for high school boys, who buy one and carry it just in case and the three packs are for college guys,, you know, Friday, Saturday and Sunday night"

The old man says, "That makes sense, but what is the 12 pack for?"

The pharmacist says, "Thats for you old guys, you know, January, February, March, April and like that."
