Hospital case

[Dilbert53]

A man is lying in hospital severely battered. The man in the next bed asks him how he came to be in that state.
Well, he said,"I walked into a pub and there on the floor was a pile of dog poo which I didn't notice. I stepped in it, skidded across the floor and banged into a wall.
And that caused your injuries?
No, said the man, what happened was a few minutes later a 6'4 20 stone evil looking bloke walks in, steps in the dogs mess, skids across the floor and bangs into the wall. Trying to be helpful I went over and said to him, I just did that.............

I think that may be even older than the Pygmy joke below!
