"Have another think" was a recent topic. Using "think" as a noun was questioned, but Winnie the Pooh uses it that way, so it must be okay.
I think this is a humorous usage that got into the language, that's all, sort of like "thunk" as the past participle of "think". But even as a joke, naturally you let it go on long enough and youngsters start to think it's valid English.
It can't be too widespread, yet. No one seems to get it when I say, "Great minds like a think."
LOL! Reminds me of a warning my boss passed on to me about two decades ago, to the effect that it'll be a while yet before we'll have really good translation software for a language in which you can say "Time flies like an arrow; fruit flies like a banana".
