What are some of your bad experiences in theatre?

That's why I do tech and because I can't act to save my life. Worse experience in a theatre was probably when I was flying a scrim out and a pipe in the bottom had wiggled loose (pipe was 5 feet longer then it should have been and it unscrewed itself over repetitively hitting the stage) and fell out 10-15 feet up, missing an actors head by inches.
