What are you in for?
You should've used our friend, Mr. Apostrophe. He can turn manslaughter into "man's laughter." and they can't lock you up for that, can they?
Did anyone ever do this joke prior to Mrs Falbo? It sounded like a "meta" joke, when she did it, but that sort of implies somebody had done it without the meta at some earlier time.
By the way, I of course realize that the Mrs Falbo character is not among those in the SCTV collage I've reproduced here. Still: the train of association runs on its neurological tracks....
