Have you ever laughed out loud when you shouldnt have?

yes, when i see funny movies.

Yes. When I was in school and college, when I could not control myself, I must have laughed and received the attention and punishment for it. Not after I grew as a adult. In reality, actually one laughs suddenly and it is natural expression.

I tend to do that a lot... sometimes in class... sometimes at movies that aren't really supposed to be funny.

Yes, the first time I saw "Silence of the Lambs" the part where Clarisse is in the prison and one of the prisoner's tell's her "I smell your c--t" I thought he said "I smell your gut" and I started laughing (I don't know why I would think that was funny) my friend's told me to shhhh!!! And after the movie they asked me why I was laughing, and they did not think it was funny either. don't know why I laughed.

Ohh indeed .. I have a terrible sense of humour .. I can see something funny even in the most serious moments .. I did have one boyfriend refuse to take me to the cinema to see horror movies because I would laugh all the way through the 'supposed' scary bits ..

We were bowling in a huge group of people once when one guy tripped, and went half-way down the lane with his arms stretched out to his sides. He sorta looked like a plane on a landing strip. I laughed so hard, I thought I was going to pee myself. No one else laughed and they thought I was terrible for laughing. Oh well, I was embarressed at the time. But just thinking about it, I'm laughing about it all over again.
