Descretely "breaking" an lcd tv. I want a new LCD tv, but need to convince the wife we
NEED one

I know with old CRT tv's you could just put a powerful magnet on the screen and it would be perma-screwed. is there anything like this for lcds?
and just to dispell the obvious, I dont want to throw something @ the screen. It would be better if it looks like it just 'failed'.
