Hard to think of one on the spot, but I have an unintentional one/mistake.

When I was a kid, my mother had a digital camera that broke. It had a mechanical lens (or I suppose “lens housing” that would extend when powering on, then retract when powering off. I guess somehow the lens got stuck in between states, and so the camera would refuse to fully boot up. A bit after that happened, she got a new digital camera.

Me being the tinkerer I was, I asked if I could mess around with the old camera and was basically given it since it was useless (or so she thought). While messing with it, I accidentally dropped it - it somehow fell at just the perfect angle and “knocked” the lens back into place (without breaking anything). Camera worked perfectly fine after that!

Unfortunately while I was still allowed to keep it, that never really “kick started” a passion for photography in me. As far as I recall I got bored of it pretty quickly.
