There are two guys, one with a Doberman Pincher and one with a Chihuahua. The guy with the Doberman Pincher says to the guy with the Chihuahua, "Let's go over to that restaurant and get something to eat." The guy with the Chihuahua says, "We can't go in there. We've got dogs with us." The guy with the Doberman Pincher says, "Just follow my lead."

They walk over to the restaurant, the guy with the Doberman Pincher puts on a pair of dark sunglasses, and he starts to walk in. A guy at the door says, "Sorry, mac, no pets allowed." The guy with the Doberman Pincher says, "You don't understand. This is my seeing-eye dog." The guy at the door says, "A Doberman Pincher?" He says, "Yes, they're using them now, they're really very good." The guy at the door says, "Come on in."

The guy with the Chihuahua figures, "What the heck," so he puts on a pair of dark sunglasses and starts to walk in. The guy at the door says, "Sorry, pal, no pets allowed." The guy with the Chihuahua says, "You don't understand. This is my seeing-eye dog." The guy at the door says, "A Chihuahua?" He says, "You mean they gave me a Chihuahua?"
