I remember as a child going up the down escalator, not far and not if there were people waiting. but it was fun. Looking down when you’re on a moving escalator is also fun but can be dangerously mesmerizing. Two classic escalator scenes are from “Elf” (https://www.youtube.com/watch?v=duiRmGxeWSQ) and one of Cato in another Pink Panther movie trying to go up the escalator while wearing fake glasses that distort his vision. Unfortunately, I can’t seem to find that one.
This, that and the other thing
