Have you ever been any place like a sick bed or a funeral home and broke out into uncontrollable hysterical laughter and could not stop?

Yes.  At my grandmother's funeral.  It was a graveside service and when the Rabbi who was hired for day said "she was a quiet unassuming woman who never asked for anything of anyone"  I burst out laughing.

I turned it into a form of art. I think I've either laughed or gotten an entire group laughing at every possible time it could be considered inappropriate. My family is a little nutty though. I'd like to think that the sick and the dead are glad people are smiling.

no, i could never do that, that is so rude
