Has Google even bothered with Foobar for like past 2-3 years? It appears so frequently on non-incognito searches that surely every developer must have seen it by now.
However, maybe I'm remembering wrong, but a few years ago I was reading an article about it and someone showed a search term that brought it up for them and I tried that term and got it. Dont remember what the search term was, but I think it was something related to one of the popular leetcode-esque algorithms I've never had to do in my hobbyist or professional work.
