Two horses are waiting in the paddock for the big race to begin. One horse tells the other, "Hey I just felt a stabbing pain in my hindquarters."

The other horse says, "That means you are going to win the race. The last time that happened to me, I won the race!"

Just then a dog trots over and says, "You idiots. They're injecting you with performance enhancing drugs. Of course you're going to win!

One horse looks at the other and says, "Hey. A talking dog."
