Can you name the athletes by the picture?

A prisoner in jail receives a letter from his wife: "Dear Husband, I have decided to plant some lettuce in the back garden. When is the best time to plant them?"

The prisoner, knowing that the prison guards read all mail, replied in a letter: "Dear Wife, whatever you do, do not touch the back garden. That is where I hid all the money."

A week or so later, he received another letter from his wife: "Dear Husband, You wouldn't believe what happened, some men came with shovels to the house, and dug up all the back garden."

The prisoner wrote another letter back: "Dear wife, now is the best time to plant the lettuce."
