Oh gee! I had a very, very similar experience once, though not when I was puppeteering. This was during a talent show at the country fair that PBS was televising one summer years ago, and I was one of the stage managers: just before the show began, I sat down in a metal folding chair that was evidently too close to the end of the stage - I went over the edge of the stage, while still the chair, and the next thing I know, I'm on the ground, looking up at a crowd of talent show contestants all circling around me like they had just witnessed a car accident. I joked with my PBS teamsters that had we been rolling camera when that happened, I could have submitted it to AFV and become very rich.I was doing Grover's near and far bit and as he was running far I leaned to far and fell down the stairs. I guess you could say that I was "stuck in character" because when I fell I screamed in Grover's voice. Also the Grover puppet went flying off of my hand and hit the wall. The kids laughed because they assumed it was part of the show and I am actually very happy that happened, It was an unplanned but funny scene
My very first day performing Steve D'Monster, just before cameras began rolling for our second pledge drive spot for the day, his entire arm fell off (because it was not sewed on well at all), but luckily, one of the others happened to have a small sewing kit in his office, so I was able to do a quick repair job just before we were back on the air.I think my weirdest experience was when I puppeteered at a birthday party, and one of the kids kept wanting to pull the puppet's arm off, and their parent didn't even say anything about it; in fact, they encouraged them to continue doing so! I eventually had to break character to tell this kid to get the **** off my puppet lol.
Luckily I had sewed it on pretty well, but from that point forward I use doll joints to secure puppet arms!
One interesting experience I had was when I puppeteered for VBS one summer: I played a construction barrel named Darrel, and he was incredibly popular with the little kids, they just loved him. One evening after my performance, a few little rugrats managed to mob our makeshift puppet stage (which was just some PVC pipes with black cloth draped over it) because they wanted to get back there and talk to Darrel, but instead were met with a big hairy man sitting in a chair instead . . . that didn't stop impressing them, though: they told me how much they love Darrel and how much they love how I do his voice and everything, so that was nice.
