There's a guy with a Doberman Pinchers and a guy with a Chihuahua.

The guy with the Doberman Pinchers says to the guy with a 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 the dogs with us!"

The guy with the Doberman says, "No problem; just follow my lead."

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

The maitre d' says, "Sorry sir, but there are no pets allowed."

The guy with the Doberman Pincher says, "You don't understand. This is my Seeing Eye dog."

The maitre d' says, "A Doberman Pinscher?"

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

So the maitre d' tells him that he can come in with the dog.

The guy with the Chihuahua sees his friend's success, so he puts on pair of dark glasses and walks in, as well.

Once again, the maitre d' says, "Sorry sir, no pets allowed."

The guy with the Chihuahua replies, "You don't understand -- this is my Seeing Eye dog."

The maitre d' takes a look at the puny little pup and exclaims, "A Chihuahua?!?"

The dog owner replies, "What! You mean they gave me a Chihuahua?"
