That's definitely the most internationally known one, I think! It's strange that such a widely known "series" has only ever had four shorts, which together might come to about the same time as the film version... but it's just as well that Peter Sallis happens to have defied the odds and is still alive (the only original Last of the Summer Wine cast member to currently hold this achievement).

I would just put a Youtube link to A Close Shave up, but incredibly the only sign of it is a part of the Terminator 2-referencing truck/motorbike chase in the middle - I was going to say that it gave away the wonderful out-of-nowhere conclusion too early, but it turns out that it really does happen in that order and I'd remembered it wrongly.
