    They might be invisible pink unicorns. That could be why we don't see them.

  20. This young guy moves to the city and applies for a job in a big, multi-department store. The manager asks if he's got any experience in sales, and the kid replies that he used to sell paint at home. The manager gives him a try. At the end of the day, the manager asks the kid how many customers he had. The kid says one. The manager says 'kid, you've got to do better than that. How much did you make in sales". The kid say 'one hundred thousand, two hundred and fifty eight dollars and 98 cents". The manager is astounded. "What did you sell"? "Well" says the kid, "the guy wanted some fishooks, so I got them, and then suggested he buy a new rod and reel. I told him if he was going to go fishing, he needed a boat, so we went to the boating department and I sold him a new Chris Craft and a trailer. Then he said his Toyota would never be able to tow the boat, so I took him down to automotive and he bought a new truck". The manager says "He wanted fishhooks and you sold him all of that?" The kid said, "No he didn't come in for fishhooks. He wanted some tampons for his wife and I said, 'Dude your weekend is already shot, you should go fishing".
