The other day I was at the coffee shop when the train delivering newsprint to the newspaper plant next door rolled in. It let out a long low whistle that sounded something like a foghorn. The barista remarked, “That always reminds me of the call to arm in Lord of the Rings.”
Which prompted one patron to call out, “The orcs are coming!” and another to leap to his feet and say, “Time to break out the battle-axes!”
Well, it was kind of an amusing moment on an otherwise quiet morning.
