Several racehorses are in a stable. One on them starts boasting about his track record. "Of my last 15 races," he says, "I've won eight."

Another horse breaks in, " Well I've won 19 of my last 27!"

"That's good, but I've taken 28 of 36, " says another, flicking his tail.

At this point, a greyhound who's been sitting nearby listening says, "I don't mean to boast, but of my last 90 races, I've won 88."

The horses are clearly amazed. "WOW," says one horse after a prolonged silence, "a talking dog!"
