Give an example of thinking outside the box

Reminds me of the old Tommy Cooper joke:
 
Or the old Peter Sellers Joke.

Man walks into a bar, and goes up to a man sitting on at the bar with a dog beside him.

First man "does your dog bite?"
Man at bar "No."
First man then bends down to pet dog, and gets his hand savaged.

First man "I thought your dog doesn't bite!"
Man at bar (shrugging sholders gallic style) "That is not my dog"
