1000 Dollars and 3 Eggs

A young couple gets married, and the groom asks his bride if he can have a
dresser drawer of his own that she will never open. The bride agrees. After
10 years of marriage, she notices that his drawer has been left open. She
peeks inside and sees 3 eggs and $1,000.

She confronts her husband and asks for an explanation. He explains "Every
time I was unfaithful to you, I put an egg in the drawer." She figures 3
times in 10 years isn't bad and asks "But what about the $1,000?" He replied
"Whenever I got a dozen eggs, I sold them."
