Hara Ra, you always have such a delightful way of creating a "play" on words.
In the actor's jargon world it's a loving pinch in the rib:
The idiom, break a leg is used to wish someone, such as an actor, success in
a performance. So, it's pretty extropian. Better, me thinks, than saying
for prosperity's sake, "good luck!" 'cause luck happens to people, and we
extropians create our own destiny.
Keep fit!
