“The Work Outing”, the episode with a vaguely similar plot which made me cry with laughter the first time I saw it, is available for free on Youtube: https://m.youtube.com/watch?v=cj490uNht4o&pp=ygUVaXQgY3Jvd2Q...

The scene where Maurice finds himself behind the bar serving drink had me crying in laughter

"I'm disabled" still makes me giggle just thinking of it.
