Big over-spenders
 

There was a couple who were big over-spenders. They always dreamed to spend holidays in Hawaii, but were never able to save any money to do so. One day they came up with an idea - each time they had sex, they would put $20.00 bill into a piggy bank.
They bought the piggy, and followed that procedure for about a year. After that time, they decided that there was enough money for their dream vacation and broke the piggy bank. The husband looked at their savings and said: "Isn't it strange. Each time we had sex, I put $20.00 into the piggy. But I see tons of $50.00 bills and a few $100.00 bills."
The wife replied, "Do you think that everybody is as stingy as you are?"
