Had an electrician buddy of mine come over to take a look at a couple weird electrical things in my house.

Queue him trying to flip a 240V oven outlet right side up as the previous electrician put it in upside down (which was why my oven wouldn’t go back against the wall). I ask him if he wants me to turn off the oven breaker. He goes “nah, I’ll be alright” and I shit you not, 5 seconds later there’s a massive bang and his hands are covered in black soot and the wall has the same all over it.

He just goes “Well, it’s off now!!”
