Always enjoy a good "how the hell did that happen" story

Back in my arcade gaming days, I ran into an extraordinarily rare glitch in Smash TV that I like to brag about.
I was fighting the first floor boss, Mutoid Man, when I apparently stepped on a land mine that was so far down the screen that it was completely obscured by the bottom wall. Suddenly the screen just went black. A while later, a message popped up that said something like "You've found the Secret Warp!". Then level 2 started.
There is no "warp zone" in Smash TV. It wasn't until many years later that I finally found out what happened. It was the game's exception handling system. If the game encounters an unrecoverable exception (aka crashes), when the hardware reboots, it recognizes it was in the middle of a game, throws up that message, abandons the current level entirely and starts the next. It's so rare that I've never even been able to find a screen shot of it.
