"There's no earthly way of knowing / Which direction we are going / There's no knowing where we're rowing / 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!"

--- Willy Wonka in "Willy Wonka & The Chocolate Factory" (1971)
