There are so many excruciating components to this 20-second video, watching one time simply won't be enough.
Witness and video creator Joe Gilmore explains:
'After leaving our office Christmas party I found this awesome fella who had had one too many sherries and was trying to walk the wrong way down the escalator.

Although it looks bad he was actually fine in the end, and we managed to get him home safely! Sure he had a nasty hangover in the morning though!'
So there you have it – he was fine, so you're allowed to laugh.
