What was the worst live performance you've ever seen?

I saw Slaves (UK rock band) back in October in a small bar. They were fantastic, but the opener was some random nobody band from Boston.

Their music was SO LOUD you couldn't hear a single thing the singer was saying. The singer made it very memorable on his own, however, by going into the crowd and bumping into people and throwing himself onto the floor. More specifically, he kept bumping into this poor old couple who were very much out of their element and will probably never see a live performance again because of this absolute goon.

During one of their final songs, he actually took his mic and walked into the men's bathroom where he continued to sing...
