Re: Comedy gold right there!
Presumably it rose with a moped on top of it, not well balanced, a man came up and started using the convenience - remember this is at night and I don't see floodlights on the top of this thing, and the moped toppled off and fell on him. Maybe he leant a hand on the thing which helped nudge the moped off (did you see it wobbling half-way through the video?) or some friends leant on the other side, waiting for him. Anyway, unless you routinely look up for falling vehicles every time you urinate, I don't think it's really fair to laugh at this. The man was apparently badly injured.
