Definitely.
I usually laugh because of insignificant details. Like once I was in my social group and we were talking about cereals and then this guy spontaneously says, 'THE FROSTIE ADVERT GUY DIED!' and then he goes into detail of the death. I was laughing because he went off topic so much, because when I first heard about it I felt sorry for the guy.
Another time I was on the way home from a trip and my ass-hole Year 6 teacher forced me to eat fruit with the skin on, and I was vomiting the whole way home. I couldn't help but laugh all the way home, because I knew he probably would have got in loads of trouble for doing so, or was at least under loads of stress because he thought so. I just couldn't stop laughing xD.
Another time I was watching Little Britain, and didn't really get to laugh 'cause it was 3AM in the morning and everyone was sleeping. Then at school, in the first lesson, I kept thinking about all the other sketches, and kept on laughing out loud xD. The worse thing was people were performing their poems. So when I came on, everyone was laughing at me(forced), and I was genuinely laughing 'cause everyone was laughing, and the whole class thought I was a jerk.
There's also been countless times where I've just been laughing to my self about how much my social life sucks, LOL.
I have a really weird sense of humour. I won't laugh at a joke everyone else laughs at, but will easily laugh at a sentence which is spelt wrong, or an incorrect eBay description.
Sometimes I'll only notice how funny something is at a really random time, like maybe half way through a conversation.
I think my random laughing is the main hint I'm 'different' xD.
