A student inquired: "Did J.R.R. Tolkien ride a mûmak?"
What gives you the silly idea that Tolkien did anything like this? It would have been highly impractical in an urban area like Oxford. The truth is, J.R.R. Tolkien always drove a British Mark I tank which he had received as a souvenir after his World War I duty.
It is true, though, that Chuck Norris rides three mûmakil at once (taped together).
