We were putting on the play "Dracula" when a friend of mine, playing Renfrew, did his dash across the stage -- and off, and into the first row of the audience. He took out three ladies and broke two toes, but his only thought was "Get on stage or the Director is gonna KILL you!" He did, and finished the scene before collapsing backstage.

Once, I was playing Ravel's "Bolero" with a band and we got lost. Everyone. Including the Director. We were trapped in the "dah, dadada, dah, dadada, da" section for three or four *minutes* before the lead trumpet stood up and took up the music several bars on. We managed to pick it up without a problem and I don't think anyone was any the wiser.
This might say something about Ravel's music, too.
