I think that the British really excel at spoken comedy. They just have a penchant for wordplay and dry wit that just cannot be matched. If you look at Ealing, or Python, or really any major British comic, you'll notice that it almost always comes back to dialogue. It's something that the Brits really do better than anyone else. Even so, there's something to be said about physical comedy too, and in that area, nothing matches Some Mothers Do 'Ave 'Em.
The tale of a well meaning but ultimately hopeless man named Frank Spencer, this series chronicles his inability to get anything right. Or more accurately, his incredible ability to get everything wrong. Where other sitcoms balanced sharp writing with occasional slapstick, this series is all about the stunts, which were actually performed by Michael Crawford. You really have to admire the spectacle here, and how the most mundane situation can turn into an epic chain of unfortunate events. Something as simple as a driving test turns into a huge spectacle, and these setpieces are damn impressive.
Michael Crawford plays Frank as a meek but well intentioned man, and that makes it funnier when even the simplest things he does become insanely huge. This show is gloriously mad, and the stuntwork is genuinely fantastic. This is one of the best examples of slapstick because it's so perfectly composed, and because it's done practically, it's fairly believable too. It's such a fun series to watch, because you never quite know what's going to happen next. This show masters the idea of comic escalation. Every episode is like it's own joke, with each individual setpiece upping the ante. Few sitcoms are as impressive to witness as this one, because few sitcoms did what this one did. Hell, there isn't really anything now doing what this did. It's crazy, and it's all the better for it. Simply put, Some Mothers Do 'Ave 'Em is an out and out classic
