The Big Turnip
Z49.9. Pulling up the turnip. Final formula: the mouse holds onto the cat, the cat holds onto Mary, Mary holds onto Annie, Annie holds onto grandmother, grandmother holds onto grandfather, grandfather holds onto the turnip - they all pull and pull it out.
ATU A man attempts to pull up a turnip. He cannot do it alone, so he calls his wife to help him; she pulls on him, he pulls the turnip, but still the turnip will not come out of the ground. More people and animals are brought in to help. At the end, a long line of helpers pulls on the turnip and it comes out of the ground.
