A couple get married and decide to have a separate draw each for private stuff. The other partner is never to look in there.

But after 20 years, the husband's curiosity gets the better of him and he looks in the draw. He finds three eggs and $120.
When his gets home, he fesses up to taking a look.

"What did you find"? she asks him. "I found three eggs and $120" the husband says.

The wife tells him that every time she was unfaithful, she put an egg in the draw.
The husband reckons that after 20 years, cheating three times isn't so bad.

"But what's the $120 for then"? the husband asks.

"Well" said the wife, "every time I got a dozen eggs I sold 'em!"
