Moi?? Nawww.

You have the carb off for a little tweaking and forget to stuff a rag into the intake. Ever drop one of those little ball check carb bearings down into the intake? Or a small nut, or socket? Or the distributor hold down bolt, or washer, or bracket down into the distributor hole?

You have the engine on a stand. The pan is on. You turn the engine over to bolt a head on and something drops, "Tink", "Tink" into the pan. You think, "Wait a minute, there's not supposed to be anything loose inside the pan".

Let's see...what other dumb and embarassing things have I done either being careless or trying to save time.
