Two men are walking their dogs. The first guy has a doberman, and the second guy has a chihuahua. They walk down the street and stop at a restaurant.
"Man, I could really go for a snack," says the first guy.
"So could I, but the signs says No Dogs Allowed," says the second guy.
So the first guy says: "Wait here, I have an Idea!"
The first guy with the Doberman puts on his sunglasses and walks into the restaurant and asks for a sandwich, and the waiter says: "Hey, no dogs allowed, didn't you read the signs?" The guy replies: "No, I didn't. I'm blind and this is my seeing eye dog." The waiter apologizes and serves him his drink.
The second guy watches all this, puts on his sunglasses and goes in. The waiter again says "Hey, no dogs allowed, didn't you read the sign?" The guy with the chihuahua replies: "No, I didn't. I'm blind, and this is my seeing eye dog.
"The waiter exclaims: "That little chihuahua?"
The second guy replies: "WHAT! They gave me a chihuahua?!"
