I often enjoy crashing into mincing kangaroos and incipient balrogs, and the crunching under my wheels is like unto the crunching of little crystals inside my head. And Tolkien approved of chewing tobacco when one had forgotten one’s pipe at home. In fact, Chewbacca was one of his creations.

Or, as the French say, “le menteur composite”.
