After a while, the man and the German Shepherd get up to leave. As they're going out the door, another man with a Chihuahua is coming in. First man says ``The bartender won't like you bringing that dog in here, but just tell him it's a Seeing Eye dog and then it'll be OK''. Second man looks dubiously at his tiny Chihuahua, thinks a few seconds, then thanks the first man and goes on in.

Bartender says ``Hey! You can't bring that Chihuahua in here!''. Man stares straight ahead and exclaims ``What! They sold me a Chihuahua?!''
