Accidents happen.

A friend of mine was playing keyboard at a dance when someone opened an exit door, and knocked over his pole mount speaker. The corner of the speaker hit him in the head and caused him to bleed. The injury looked worse than it really was because he was taking a blood thinner. He was rushed to the hospital and fortunately his medical insurance took care of the bill.

Good thing it hit him not his keyboard. The keyboard wasn't covered.

The next time he played there, he wore a hard hat, and the audience found it pretty humorous.
