When you just can't stop...

I love to laugh. It's wonderful. Don't you love it when you're laughing uncontrolably and can't stop no matter how hard you try? It's so much fun. So, here's my question... What makes it so I can't stop laughing? What does it take to get to that point?
The first thing I need to make me laugh like crazy is to be in the mood. Then, something has to set it off to start the giggles. Usually, there's a gradual increase in humor, and then the big thing (or little thing that appears really funny) happens, and starts the uncontrolable laughter. I love that feeling...to be laughing from deep inside, exerting all of your strength towards the laughter that you can't hold in. Those are truly good and memorable times.
The second thing that makes me laugh like crazy, is to be laughing already. Sometimes it can be funny to laugh at laughter. Believe it or not, laughing can be really funny in itself. It is truly possible to laugh at laughing. That can set off the domino effect, creating an irrisitible giggle that grows into "rolling on the floor laughter."
The third thing that makes laughter uncontrollable is the laughter that comes when you're not supposed to laugh. For exampe, in ninth grade, one of my teachers (unnamed for protection) was walking up the aisle between our desks when... well, let's just say that a normal bodily function (sound-oriented) occured. This function lasted from the back of the classroom up to her desk. Now, only the student behind me and myself heard this bodily function. Now, in many other settings, it would have been ok to laugh, but not then... not when it was a teacher whom I was to respect. Now, I cannot begin to describe the difficultly the two of us were having in containing our nearly irripressible giggles. I must admit that several escaped me, but I did my best to cover them up. I had to use all of my might to keep myself from embarassing my teacher. This is one of those times when laughter just comes naturally, merely because it's not supposed to. I was finally able to laugh while retelling this story to my family. It is likely that I was laughing too hard to speak or breath. Good times.
The fourth reason we laugh like this is because something truly funny does happen, and you simply cannot contain it.
The final reason that I think that laughter can become irrepressible, would be that you simply need a truly genuine laugh. In this case, your laughter can be sparked by many things. Funny, stupid, ridiculous...anything can start a good laugh when you need one.
I love to laugh. Don't you? Uncontrollable laughter (like when Mr. Rich puts his hands on his knees, cannot breath, and actually starts crying) can create wonderful memories (especially if it's genuine clean humor)! Such laughter can be sparked by my mood, something stupid, something ridiculous, something humorous, something gross, something truly funny, anything, or nothing at all. It's wonderful. Good night.
