There's no such thing as a slippery slo..... ahhhhhhhhh we fell off the mountain!!!!!

because it became "assault "to hit someone when they did something stupid. The hit is for when they are too stupid for words to mean anything to them. It also means that there is something they don't understand that they should try to figure out or ask someone else who can. This encourages cooperation and social skills. Without that hit, those skills go away and we get retards who cant hold or turn a screwdriver or a pipe wrench.
