Unintentionally Funny Moments on Film/Television/Stage

So, I recently viewed clips of the Les Mis death scenes (so that when I actually do see the film I won't be a crying mess). Turns out that I didn't cry, but there was this one death scene that I just found hilarious:

Javerts Suicide

I know this scene was not meant to funny, and I really tried not to laugh, but couldn't help it. I laughed mainly because of the large "crack" noise, and the CGI body landing vertically head first, and then after that large "crack" his body just gets washed up. That just seemed like something you would see on Family Guy, or some comic movie.

Now, I'm pretty sure that scene was just funny on screen, and I know there are others who feel this way about that scene.

Are there any scenes you've seen that you just couldn't help laughing at, even though you you weren't supposed to?

I got the hysterical giggle fits during Ordinary People in the movie theatre. Everyone around me were openly sobbing and a woman next to me loudly blew her nose and I LOST IT! I had to get up and go to the lobby.
