“Theres no earthly way of knowing
Which direction they are going!
Theres no knowing where theyre rowing,
Or which way the rivers flowing!
Not a speck of light is showing,
So the danger must be growing,
For the rowers keep on rowing,
And theyre certainly not showing
Any signs that they are slowing. . . .”

—Willie Wonka, in Charlie and the Chocolate Factory by Roald Dahl, 1964.
