As a painless way to save money, a young couple arranged that every time they have sex, the husband put his pocket change into a china piggy bank on the bedside table.

One night, while being unusually athletic, he accidentally knocked the bank to the floor where it smashed. To his surprise, among the masses of coins, there were handfuls of five and ten dollar bills.

He asks his wife what's up.

"Well," she replied, "not everyone is as cheap as you are."
