I can't remember the last time using the phrase, but there's no reason I couldn't. If I were to, then I'd shorten it to "all work and no play", implying the rest, which sounds rather cliché. I'd be surprised if a native English speaker hadn't heard it echoed dozens of times in some form already.

The one I still remember best was from The Simpsons, back when they were still funny. They had a take on The Shining in their Halloween special Treehouse of Horror V:

Homer - "No TV and no beer make Homer something something."

Marge - "Go crazy?"

Homer - "Don't mind if I do!"

I'm learning Polish, so I had to look up what the appropriate phase might be. Of course I don't think there's any good direct translation, but the closest seems to be "<em>Nie samą pracą człowiek żyje</em>", or something like "one does not live on work alone", which mirrors the biblical verse with bread. I could find lots of demotivators with the phrase, so it seems common enough.

only saw it in the shining. such a good movie! 😫

I had seldom heard anyone use "All work and no play makes Jack a dull boy" before the "The Shining" came out. It was the kind of disused proverb that most people knew from listening to their grandparents or from reading books written in earlier times.

I still don't think I've ever heard it used in earnest. After "The Shining" came out, though, it slowly took on a new life as a saying meaning: "I've been doing something crazy, and now I'm about to do something crazier." It's usually accompanied by an attempt to imitate Jack Nicolson's voice and weird-eyebrows-&-crazy-eyes expression.

This is the best example I can think of:

You and I and some friends are camping way out in the country, near a grassy open field. It's late in the evening and we're being silly (maybe we're a little bit drunk :). We've been running around the field with our arms outstretched, imitating jet engines noises and pretending to be airplanes, like we were little kids on a school playground. It's a clear night, there's no rain in the weather forecast, and someone says, "Wow - the only way this would be nuttier would be if we were all using the rain flies of our tents for wings or something."

I stop running, and in my best (not very good) Nicholson, say: "Ha-ha! All work and no play makes Jack a dull boy! - And Evelyn a dull girl!" I run over to my tent, grab the rain fly, throw it over my shoulders, and start swooping around the filed with my "wings" streaming and flapping behind me.

I would say anyone in The UK above 50 years of age/fifty years old will know and would have used the full expression. "All work and no play makes Jack a dull boy", that is possibly linked to "Jack" in the nursery rhyme "Jack and Jill went up the hill"

I think "Don't mind if I do" reflects the use of using negatives in the English language, that is perfectly acceptable and used appropriately by native born English speakers or anyone who learnt/learned English from a very young age would know how to phrase such negative sentences. The teaching of "double negatives" as always being wrong and incorrectly identifying double negatives by some teachers may have lead to such negative usage statements dropping out of fashion. But I am not a linguist. Let's see what any linguists have to say.

Regarding learnt/learned the addition of a T to reflect the past was very common by Brits across many words. Now learned is also used in the UK. My thoughts on the few words remaining where we Brits or older Brits still instinctively say and write the "t" are:

in no particular order

These three are refusing to die, you will hear them constantly used by Television presenters in the UK.

Prince William of the British Royal Family seems to use the supposed American in his speech.

Saying Learned and burned but still uses meant and not meaned that is not in a dictionary and sounds totally off to everybody's ears.

Definitely heard it often. Although we tend to say just the first half, possibly because the second half sounds a bit dated, but also because it is too long!

You often hear it in a half-teasing, half-caring kind of way.
