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, okay 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?
