Worst and kinda the best was at a local metal band rally. My friend's band was going to perform and my brother and me were at the edge of the mosh pit. Some punk trying to be hard core and kicked at my brother, who in turn, dropped him with a punch. Before we knew it, huge brawl and we were kicked out after we broke one of the security guy's nose.

Oh, and we never did see my friend perform. Eh, still, it was a blast.
