One time there were five of us on an escalator and my buddy got his shoelace trapped as he was stepping off and fell to his knees, there was a train of us going "OH GOD NO" as we were moved ever closer, two of us had to leapfrog over him. He had to pull his laces out so hard it made him do a roll.

Not looking for advice btw, I know how one is supposed to live and how to both solve and not originally have this problem, but am, on occasion, a fool.
