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 bar 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 bar and the guy
with the Doberman put on a pair of dark glasses and started to walk into the bar.
  
The bouncer 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 bouncer said, "A Doberman Pinscher?"
  
The man said, "Yes, they're using them now.  They're very good."
  
They bouncer said, "Okay, 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 bar.  He knew his story would be a bit more unbelievable.  Once again, the bouncer
said, "Sorry, pal, no pets allowed."
  
The man with the Chihuahua said, "You don't understand.  This is my seeing-eye dog."
  
The bouncer said, "A Chihuahua?"
   
The man with the Chihuahua said, "A Chihuahua?!?  A Chihuahua?!?  They gave me a darn
Chihuahua?!?
