Laughing

I was reading an article today on MSN about uncontrolable laughter and how sometimes it happens at very inappropriate times. So I am curious as to moments that this has happened to you? Share your interesting moments! Mines below

I remember one time in an American Literature class that a friend and I burst out laughing at a horrible time. It was when we had to watch the move Of Mice and Men. In the ending one of the main characters has to shoot his friend, because he is slightly retarded and is unable to control his own strenght because of it and accidently murders a woman. Well in the book, which we read before seeing the movie, explains the scene as a very sad emotional part. Then when you watch the movie they build up to the moment and then the guy simply shoots him and his friend just plops forward dead. Well my friend and I, obviously having similiar humors, simply bust out laughing at how anticlimatic it was. The class had been completely silent throughout this whole time, so of course everyone heard us and we got some pretty nasty stares. We had to explain ourselves since half of them in there thought we were laughing because he died. Ha that was an interesting moment, and makes me laugh just thinking about it.
