Two buddies were out for a Saturday stroll.  One had a Doberman and the other had a Chihuahua.  As they sauntered down the street, the guy with the Doberman said to his friend, "Let's go over to that restaurant and get something to drink."

The guy with the Chihuahua said, "We can't go in there.  We've got dogs with us."

The one with the Doberman said, "Just follow my lead." They walked over to the restaurant and the guy with the Doberman put on a pair of dark glasses and started to walk into the restaurant.

The waiter at the door said, "Sorry, Mac, no pets allowed."

The man with the Doberman said, "You don't understand.  This is my Seeing-Eye dog."

The waiter said, "A Doberman pinscher?"

The man said, "Yes, they're using them now.  They're very good."

The waiter said, "OK then, come on in."

The buddy with the Chihuahua figured he'd try it too so he put on a pair of dark glasses and started to walk into the restaurant.  He knew his story would be a bit more unbelievable.  Once again the waiter said, "Sorry, pal, no pets allowed."

The man with the Chihuahua said, "You don't understand.  This is my Seeing-Eye dog."

The waiter said, "A Chihuahua?"

The man with the Chihuahua said, "A Chihuahua?!?  A Chihuahua?!? They gave me a Chihuahua??
