A colloquial phrase meaning crazy, mentally unstable, or simply eccentric in a way that's hard to explain. 'Funny in the head' has that familiar folk-wisdom quality — it doesn't diagnose, it just observes that something upstairs isn't quite right. The phrase can be used critically about genuinely erratic behavior, or more lightly about someone who's just a bit odd or quirky. It's been part of informal English speech for generations and still rolls naturally off the tongue.

Everyone on the block thought Old Harold was a bit funny in the head but he was harmless enough.
