" You can work it out by Fractions or by simple Rule of Three, But the way of Tweedle-dum is not the way of Tweedle-dee. You can twist it, you can turn it, you can plait it till you drop, But the way of Pilly-Winky’s not the way of Winkie-Pop! "

― Jonathan Swift , The Adventure Collection: Treasure Island, The Jungle Book, Gulliver's Travels, White Fang, The Merry Adventures of Robin Hood: Gulliver's Travels, White ... Treasure Island (The Heirloom Collection)
