A barber says, "I shave anyone who does not shave himself, and no one else." But does the barber shave himself? If he does, then he mustn't, because he doesn't shave men who shave themselves. But then he doesn't, so he must, because he shaves anyone who doesn't shave himself... Both possibilities lead to a contradiction.

I love that one .. there is also one about angels and making a choice .. does that ring any bells?

Yes .. something like that .. As I remember you are in purgatory and are given a choice by an angel but you don't know whether the angel is good or fallen .. maybe I'm mixing my riddles 🙄

Simple... the barber doesn't need to shave herself.
