So Im thinking that may be the cause of my insanity. What you think?
Well you certainly didn't knock any sense in.
Mind you, I've had a couple of knocks on the head and got no wiser, either.
Besides, insanity is only a state of mind.... and if you don't mind, it don't matter.
It was like the time a doctor was looking in my ear with one of those light gadgets. He said to his colleague: "Oh look, nobody's home."
Hmmm, I wondered why there was a beam of light shining on the opposite wall.
