The ground is always on the top. Cause if a piece of wire or
metal drops behind the plug, the ground keeps it from
shorting the two flat prongs.


Yea but if the ground is on top and orange juice spills in it, the ground
will divide the water left and right just beyond the prongs (regardless of
liquid volume, velocity, viscosity, wind, gravity, sunspots, etc) and
effectively nothing happens. Ask MacGruber.
