MY HARDEST RIDDLE!
Question: There is a story that a man and not a man
Saw and did not see a bird and not a bird
Perched on a branch and not a branch
And hit him and did not hit him with a rock and not a rock.
[How is this possible?]
A eunuch who did not see well saw a bat perched on a reed and threw a pumice stone at him which missed.
