Some race horses staying in a stable. One of them starts to boast about his track record. "In the last 16 races, I've won 8 of them!"

Another horse breaks in, "Well in the last 27 races, I've won 20!!"

"Oh that's good, but in the last 37 races, I've won 29!" says another, flicking his tail.

At this point, they notice that a greyhound dog has been sitting there listening. "I don't mean to boast," says the greyhound, "but in my last 91 races, I've won 89 of them!"

The horses are clearly amazed. "Wow!" says one, after a hushed silence. "A talking dog."
