A guy with a Doberman Pinscher and a guy with a Chihuahua decide to go to a 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 Pinscher replies, "Just follow my lead."

They walk over to the restaurant, the guy with the Doberman Pinscher puts on a pair of dark glasses, and he starts to walk in.

"Sorry, Sir.  No pets allowed," announces the door man.

The guy with the Doberman Pinscher says, "You don't understand. This is my seeing-eye dog."

The door man inquires, "A Doberman Pinscher?"

He responds, "Yes, they're using them now, they're very good."

The door man says, "Come on in."

The guy with the Chihuahua thinks, "What the heck," so he puts on a pair of dark glasses and starts to walk in.

"Sorry, pal, no pets allowed," announces the door man.

The guy with the Chihuahua says, "You don't understand. This is my seeing-eye dog."

The door man inquires, "A Chihuahua?"

The guy with the Chihuahua replies, "You mean they gave me a Chihuahua?"
