Greyhound and Horses

Three race horses were bragging about their race averages.

"I won 5 out of 20 races," said the first horse.

"Oh yea! I won 15 out of my 30," said the second.

"Hah! I won 50 out of 60," said the third.

Hiding behind a hay bail, a greyhound was listening in on the conversation. He steps into view and says. "Well I won 99 out of 100 of my races."

The third horse looks at the second horse and says

"WOW!!.... A talking dog!"
