Jokes that have never produced laughter, Vol. 2

A man goes into a bar. He has a dog with him. The dog is wearing an eye patch. The man says to the bartender, "Ask me about my dog." Unfortunately, the bartender does not hear him, because he went deaf in one ear as a child. He serves a woman at the other end of the bar. When he comes around to the man with the dog again, the man orders an imported beer. He forgets what he was going to say about the dog.
