This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Except that if a plug falls out, you want it to stay grounded... meaning the ground should absolutely be on the bottom because gravity.
Not necessarily. You typically want the ground longer so it's the first in and last out. Type G has the ground on top. I vaguely remember hearing that's because if it comes slightly out and something sharp or metal falls on the plug, you want it to hit the ground and not the live part...but I don't know how reliable that story is.
This is the reason, yeah, at least according to what I’d read on Wikipedia (I’d just learned this “funny story” myself a few minutes before reading the comment above). I wanted to see if there was anything that could confirm it, but I’m not paying $70 to purchase the standard (NECA 130-2010) where it may be written.
Some electricians started doing it since it became a viral Internet trend to intentionally drop quarters onto the prongs of a slightly pulled out plug.
In history there’s only been a few cases of a fires being started because of an accidental thing falling on the plugs. The breaker trips before a fire would start in almost all cases. Provided the breaker isn’t faulty or something. Which you should be testing regularly as a home owner.
