A man walks into a shop and sees a cute little dog. He asks the shopkeeper, "Does your dog bite?"
The shopkeeper says, "No, my dog does not bite."
The man tries to pet the dog and the dog bites him.
"Ouch!" He says, "I thought you said your dog does not bite!"
The shopkeeper replies, "That is not my dog!"
