Chihuahua

A guy wanted to take his Chihuahua into a restaurant with him, so he put on dark glasses and "tapped" his way into the establishment.

The waiter said "Hey!, you can't bring a dog in here."

The man indignantly claimed "I'm blind! ... this is my Seeing Eye dog!"

"You're trying to tell me" said the waiter, "that this Chihuahua is a Seeing Eye dog?"

"What???!!", cried the man, "they gave me a Chihuahua?"
