Post your quirks, and see your friends instantly become disgusted with you!

I laugh spontaneously, sometimes even in my sleep, one time I laughed so hard I woke up with my ribs hurting. Is this weird?

Laughing is fun. I laugh at many, many things, even when it would probably be inappropriate or unfunny.

Laughings not weird. I frequently attempt to forecast how social interactions will go, sometimes months in advance - and you'd think this amount of contemplation would allow me to better handle when my predictions are proven right, but no, I end up grinning ear to ear like a maniac stammering back and forth between whatever it is I need to be saying in that situation and "I fucking knew it! YEAH!"
