A relative has asthma. While watching Monty Python and the Holy Grail once, he laughed so hard, so the story goes, that he had an asthma attack and fainted during the Black Knight sketch. People around him were laughing so hard they didn't notice until he started moaning as he was coming around. He still tells this story.
LOL! That's actually funny, in retrospect, since he was alright. I've had to leave the room and run outside, when cold, for a breath. We, too, laugh at Monty Python. My son has the mild asthma like I do, and he also has laughing as a trigger, so we crack up trying not to make each other laugh. It can be really funny.
