After 20 years of marriage

A young couple gets married, and the groom Clarence asks his bride Carolyn if he can have a dresser drawer of his own that she will never open. The bride agrees. After 20 years of marriage, Carolyn notices that his drawer has been left open. She peeks inside and sees 4 golf balls and $1,000. She confronts her husband and asks for an explanation. Clarence explains "Every time I was unfaithful to you, I put a golf ball in the drawer." Carolyn figures 4 times in 20
years isn't bad and asks his husband "But what about the $1,000?" Clarence replied "Whenever I got a dozen golf balls, I sold them"
