I know a thing or two about nervous laughter.
My mom was always frustrated when trying to discipline me, as I invariably had to suppress fits of giggles when she became serious with me. I rarely ever misbehaved, so when she tried to use discipline, it wasn't shaming for me but comically foreign. That often led to me being in slightly larger trouble.
I also could never help but giggle during funerals, prayers, serious family discussions, hospital visits, tragic stories about a hurt or lost loved one, heartfelt apologies or confessions, and many more no-laugh situations. Countless times I have cramped my abdomen trying to quiet waves of hearty chortling at inopportune moments. =S
I share your pain.
I believe this is what happens, like, I feel bored, and I can't stay focused on the subject, so, my mind ends up thinking of irrelevant things. I may even end up thinking of something funny, accidentally of course. I often think of what I am going to say to others whilst they're speaking, but, I end up thinking so hard, that I think of their response, to the point I think of an extremely funny situation.
But, if it is a funeral or things like that, it's more rare that I laugh. More often, I fart, yawn, etc. Like, in band, when we were performing the national anthem, I COULD NOT stop yawning during the rests, and I had a hard time stopping myself from farting, only my friend noticed, because I warned them.
