Hans Grunding has to be careful when he takes his Thrills in the Hills Circus to small towns. Some of the bridges just can’t handle the weight of a whole herd of elephants in a single van.
So before they get to the river crossing he stops the entire caravan, unloads all seventeen elephants and the six mice that accompany them, and ties them together with ropes into a long animal chain. Then they walk single-file over the bridge without exceeding the weight limit.
As he guides them, he sings a verse from a grand old tune, “You unload twenty-three tons and what do you get? Across the river with nary a fret.”
