MY mom woudl always tell us kids "don't hang your hands out of the car when I'm driving or they will get chopped off"
I grew up thinking there were really creepy people who drove around incars with knives chopping off little kid hands just for kicks.
It never dawned on me until I was an adult that my mom meant that it would happen if she got in an accident.
My brother, it turns out, believed the same thing his whole childhood as well.
