Oil leak behind the cam

I'll go you one better.
Once upon a time; I had the carb off my car, and the fuel line pointing sort of at the windshield.
For some reason that escapes me, I wanted to bump the engine over. So I just twisted the key and released. And instantly I had a fire under the hood. I mean instantly.
And you know what us cowboys do when a carb backfires and you get an intake fire, right? Sure as heck, my reflexes hit the key to suck the flame down. About a millisecond later I realized my mistake and started yelling Fire! Fire! I jumped out and starting pushing MY FLAMING car, out of the shop with every ounce of power I had, still yelling Fire! Fire! Just as I got the car out, my BOSS comes racing out with the fire extinguisher (I had no idea where it had been hiding), and he let her have it. Total time IDK maybe 10 seconds.
But my Boss was a smart cookie; he actually put the shot right where it needed to be, with just the right amount, and clean up was minimal.
Now, EVERY time I take a carb off, I remember that event. It is permanently emblazoned in my memory.

I fold!! It's good to know I'm not the only one who does foolish things. But hell, if we didn't make mistakes, we wouldn't have any stories to tell!
