Inflation

Inflation was getting out of hand, so Joe suggested to his wife, Louise, that they try a unique way to save some money on the side.

"Every time I lay you, I'll give you a dollar for your piggy back," he said.

A few weeks later, they decided to open the piggy bank. Out tumbled a bunch of dollars, but these were mixed with a rich cluster of fives, tens, and twenties.

"Louise," asked Joe, "where did you get all that money? Each time we fucked I only gave you a dollar."

"So?" she said. "Do you think everyone is as stingy as you?"
