Video of a drunk guy in a suit trying to go down an UP escalator in London is a hit online.
He wouldn't even stop when a woman and a bunch of other people tried to help him. Then after about two minutes, someone finally hit the "emergency stop" button and yanked him back onto the platform.
(At :35, a woman tries to help him, but he won't let her. They finally hit the stop button and pull him back at 2:22.)
