Several of us love using the Russian folktale about the giant turnip in storytimes. We have a flannel board of the story, but there are also plenty of books that tell it. You can read the text of the story here. After telling the story, kids can act it out. Ask for volunteers to come up and play the different parts, starting with the old man. He pretends to pull as hard as he can on invisible turnip leaves. Each time a person/animal is added, they hold on to the waist of the person in front of them and they all pull. Kids love being chosen to be the mouse, who helps the group finally succeed in pulling up the gigantic turnip.
