A dog walks into a bar and hops up onto a stool. He looks the bartender in the eye and says, "Hey, guess what? I can talk. Have you ever seen a talking dog before? How about a drink?"
The bartender thinks for a moment and says, "Sure, but first I need to see some ID, as I do not believe that you are over 21 years of age in human years."
The dog agrees that really, legally and technically, he should be in a bar, nor drinking alcohol.
He leaves immediately and apologies for wasting the bartenders time.
