What if a horse wanted to ride you instead?
Which reminds me of a joke : One day, a man and his horse took the dog running in the field, they ran and they ran and then ran, then they stopped to take a break. Suddenly the dog said, "Man! I'm so tired!!" The man was so scared that he jumped on the horse and then they rode off as fast as they possibly can. They stopped, the man said, "Oh shit, did we lose him?! ", then the horse said, "I didn't know that dogs could talk!!"
