I've seen a lot of strange and unexpected things happen at shows. I've seen stage platforms give way. I've seen entire sets fall over actors (thankfully no one was injured), I've seen audience volunteers walk off the stage. And there was that one time when a smoke machine caused a cape to catch fire...
I haven't performed often enough to experience anything like that. Best I can do is report a family member who zealously tried to make a fool out of grade-school-me (boy was he surprised when he opened his hands to find an entire family of sponge rabbits!), and the suggestion of "Abracadabra, hey presto!" as a magic "word" by a grade-school student.
I'm sure a number of you have some juicy tales to tell though, and I'd love to hear them!
I'll let James Alan start you off with this video from his Reality Based Magic post, "The weirdest thing to ever happen to me on stage."
And now, over to you. What's the strangest thing that's ever happened to you during a show?
