I’m newish to this game so I apologize if it’s already been addressed. After three groups have been found, do you only consider the puzzle to be solved if you figure out the fourth connection?
Perhaps some do, but I don’t. If I get 3, then I have solved the puzzle.
Although I believe you don’t get a score (perfect, great, phew, etc) unless you complete all four categories. And once you’ve done three, the fourth is simple so why not complete it?
I don’t care about my score but of course I would complete it if only to satisfy curiosity. I was more asking about what you personally consider completed.
Complete is all four categories. Edited to add, the game could just close the fourth category automatically after the player gets the third one but it doesn’t do that.
I do spend some time trying to figure out the fourth category but not nearly as much effort as solving the rest before I give up.
I discounted Jungle as a Music category because the only context I heard for that term was that it was something racist people called rap back in the 80s. So yeah, I didn’t get today’s puzzle.
Never give up. Never surrender.
I try to figure out the last one assuming I don’t know it right away but after a minute or two I will just click them.
I wonder if “celery apples walnuts grapes” will ever be a category.
I almost went down the primrose path looking for Addams family words, but figured it was a trap. After that it was straightforward.
Things that have no fucking business in potato salad?
As every British comedy fan knows, those are the ingredients in a Waldorf salad.
I seem to recall a previous Connections game in which one group included Cobb salad ingredients.
The Waldorf salad question was on Only Connect. It was in the sequences round, so they were in a specific order, and the challenge was to name the fourth in the list.
Only Connect is considered comedy? I’ve seen a few episodes and it seems a serious game.
The question on Only Connect was based on a scene in Fawlty Towers.
Sadly, The NYT has bullied this site down. I went to try my hand at the above-mentioned 11/22 puzzle, and wasn’t able to. 
Th New York Times has itself made previous Connections games available to play
But only to subscribers, which I am not. The argument is not worth getting into here, but I don’t plan to become one either.
