I had a school friend who was in a play. I wished her, 'break a leg.'...Um...The next thing I know, she is at the bottom of some stairs with a broken foot.
I guess I jinxed her very well.

Gh, when I was in a dance rehearsal for West Side Story, I tripped another actor and he broke his foot. (I was removed from the major dancing numbers.)
