Two things. First, it is terribly funny and secondly, I am sorry for your disaster.
Change oil enough times and I can assure you, errors happen.
As a youngster with long hair, I had just changed the oil in my car. I fired it up to check for leaks. As I bent over to look underneath, I dipped my long hair in the drain pan, realizing ir when I stood up with oil running down my head and all over my clothes.
Rebuilt an engine on a SuperMoto (a style of motorcycle, a sort of hybrid). Bike was spotless. Maiden ride. Seems the valve cover casket was not seated right. Oil all over my bike.
A few years back, dealer did an oil change on my truck (for $20, I'll let them do it-they have free donuts). a week later, I smell burned oil and see whiffs of smoke. Pop the hood, no fill cap! The oil monkey forgot to put it on.
I am sure there are plenty more episodes I've dealt with first hand. I'll skip the drips and splashes that seem to happen EVERY SINGLE time that make me feel like a dofus.
