A young newlywed couple were too poor to go on a honeymoon.
The husband came up with an idea: every time they had sex, they would each put a dollar into a piggy bank. When they reached their first anniversary, they would open the bank and use the money it contained for their honeymoon.
All went well for their first year, and on their anniversary, they broke open the piggy bank. It was crammed full with dollar bills. To the husband’s surprise, it also contained many $5, $10, $20, $50, and even $100 bills.
“What’s going on?” he asked. “I thought we agreed to put a dollar in each time.”
“Well, we did,” said his wife. “But not everyone is as stingy as you are.”
