hard

This old one runs forever, but never moves at all. He has not lungs nor throat, but still a mighty roaring call. What is it?

Common Wrong Answers

River

While a river flows and can run endlessly, it does not fit the description of 'never moves at all' as it is constantly in motion.

Clock

A clock does run continuously, but it has moving parts and does not have a 'roaring call'—instead, it ticks or chimes.

Wind

Wind can certainly create a 'roaring' noise, but it is not an 'old one' that runs forever in a stationary sense; it is always moving.
