The first guy said, "No? Watch this."
So he put on some dark glasses, acted like the German Shepherd was a seeing-eye dog, walked into the bar, and ordered a drink. And no one said anything. So the second guy took out some dark glasses, slipped them on, and walked his Chihuahua into the bar.
The bartender said, "Sorry, we don't allow dogs in here."
And the man said, "It's okay. It's my seeing-eye dog."
The bartender laughed and said, "This Chihuahua is your seeing-eye dog?"
And the guy said, "They gave me a Chihuahua?"
