Almost forgot this one, but when I was in NYC my brother was telling me how his friend almost got into a fight with a guy at a party. My brother's friend had decided he didn't like the guy for some reason, and they were having a heated exchange. And then, according to my brother, they had a dance-off.
The best part is that I can't get a satisfactory explanation for how you go from threatening to punch someone's face in, to seeing whose got the best moves on the dance floor. I'm not sure there would ever be a good enough explanation for that, really.
In any case, his friend apparently fell through a glass table while trying to do a handstand, and that's how the fight/dance off ended. He got served.
