Ah, I've seen those. I would fail oh-so-horribly. I laugh at other people laughing, I laugh at things that are barely even funny. IN school today, my teacher was trying to break up this huge argument between me and this other girl, and we were both screaming at each other, and when the teacher finally broke us up and tried to calm us down, the other girl just facepalmed and gave me the, "I'm 10,000% done with you" look, I just started chuckling.
