Can you name the athletes by the picture?

Little Tim was in the garden filling in a hole when his neighbor peered over the fence.
Interested in what the cheeky-faced youngster was up to, he politely asked, "What are you up to there, Tim?"
"My goldfish died," replied Tim tearfully, without looking up, "and I've just buried him."
The neighbor was concerned, "That's an awfully big hole for a goldfish, isn't it?"
Tim patted down the last heap of earth then replied, "That's because he's inside your stupid cat."
