A young couple gets married, and the groom…

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 30 years of marriage, she notices that his drawer has been
left ajar.
She peeks in and sees 3 golf balls and $6,000.
She confronts her mate with her findings, and asks for an explanation.
He explains “Every time I was unfaithful to you, I put a golf ball
in the drawer.”
She figures 3 times in 30 years isn’t bad. But what about the $6,000?
He explains “Whenever I got a dozen golf balls, I sold ’em!”
