Bitten ear
Nasreddin Hodja

Two men came before Nasreddin Hodja when he was magistrate. The first man said,
- This man has bitten my ear -- I demand compensation.
The second man said,
- He bit it himself.
Hodja withdrew to his chambers, and spent an hour trying to bite his own ear. He succeeded only in falling over and bruising his forehead. Returning to the courtroom, Hodja pronounced,
- Examine the man whose ear was bitten. If his forehead is bruised, he did it himself and the case is dismissed. If his forehead is not bruised, the other man did it and must pay three silver pieces.
