A dog walks into a bar and the bartender says, "what will it be" and the dog says, "I'll have a dry Martini with an olive please" the barman is amazed and says, "holy smoke, a talking dog, you could probably get a job in a circus or something!"
And the dog says "Why, do they need an electrician too?"
This joke has been cut down from the much better constructed original and is now logically flawed. Why did the barman ask the question if he wasn't aware the dog could talk ?
