Willy Wonka: "There's no earthly way of knowing..."
Henry Salt: "He's singing."
Willy Wonka: "...which direction we are going... There's no knowing where we're rowing..."
Henry Salt: "Rowing."
Willy Wonka: "...or which way the river's flowing. Is it raining? Is it snowing? Is a hurricane a-blowing? Not a speck of light is showing... so the danger must be growing. Are the fires of hell a-glowing? Is the grisly reaper mowing? Yes, the danger must be growing for the rowers keep on rowing! And they're certainly not showing... any signs that they are slowing!"
