A man is showing his dog to a group of people.  "This is no ordinary dog.  This dog can talk!"  Nobody believes him.  "Ok, I'll prove it...Dog, what does sandpaper feel like?"
"Ruff!", The dog replies.  Somebody in the crowd responds, "He didn't talk--He barked!"  The man says, "Ok, let me try it again...Dog, what is on top of a house?"
"Roof!" replies the dog.  "He still didn't talk--He barked again!"  Called someone from the crowd.  "Ok, lets try again...Dog, Who was the greatest baseball player of all time?"  "Ruth!", said the dog.  The crowd finally lost interest and left.   The dog looked up at the man and said, "Was I supposed to say Reggie Jackson?"

Tee hee Jim
