A man was standing on the curb reading a newspaper, A great big dog was curled up at his feet.  Another man came up and inquired, "Does your dog bite?"

No replied the man with the paper The other fellow reached down to pet the dog, which just about bit his hand off!!!

"I thought you said your dog didn't bite," the man screamed.

"That ain't my dog, Mister," the first man replied!!!!!
