Two friends run into each other while walking their dogs. One suggests lunch. The other says, They wont let us in a restaurant with pets.

Undeterred, the first guy and his German shepherd head into the restaurant. The maître d stops them, saying, Sir, you cant bring your dog in here.

But I'm blind, the man replies, and this is my guide dog.

The maitre d, apologizing profusely, shows both man and dog to a table.

His friend waits five minutes, then tries the same routine. You have a Chihuahua for a guide dog? the skeptical maître d says.

A Chihuahua? the man says. Is that what they gave me?
