Two men who are out walking their dogs meet on a street corner.
One says to the other, “Boy it sure is hot today. I’d really like to go into the bar and get a beer, but the sign on the front door says, ‘No Pets Allowed,’ and I can’t leave Fido alone on the street.”
The other man replies, “No problem, just stand by the door and watch me, and you’ll be having that beer real soon!”
The second man reaches into his pocket and puts on a pair of dark sunglasses, and then walks into the bar. The bartender looks up and says, “Hey buddy, you can’t bring that dog in here!”
The man says, “But I’m blind, and this is my seeing-eye dog!”
The bartender says, “Oh, OK then.” The man drinks his beer and leaves.
The first man then puts on dark sunglasses and goes into the bar. The bartender looks up and says, “Hey buddy, you can’t bring that dog in here!”
The man says, “But I’m blind, and this is my seeing-eye dog!”
The bartender says, “Oh really? I’ve never heard of a Chihuahua seeing-eye dog!!”
The man, thinking quickly, blurts out, “Oh, man! You mean they gave me a Chihuahua?!?”

Interesting Fact: In prehistoric and historic time, Inuit peoples wore flattened walrus ivory “glasses,” looking through narrow slits to block harmful reflected rays of the sun. It is said that the Roman emperor Nero liked to watch gladiator fights with emeralds. These, however, appear to have worked rather like mirrors. Sunglasses made from flat panes of smoky quartz, which offered no corrective powers but did protect the eyes from glare were used in China in the 12th century or possibly earlier. Ancient documents describe the use of such crystal sunglasses by judges in ancient Chinese courts to conceal their facial expressions while questioning witnesses.
