My grandfather worked as an assistant mechanic.
Once, a small station opened near a village. There is a train on the rails, a scene was built near it, where an important uncle tells the people about such an important event. They listened mostly to women and children.
And then my grandfather looks out of the train and cries, “Come away, grandmother! The train will turn!”
People rushed out of the train. After a few seconds for them came, everyone laughed, and began to pull back to the stage.
My grandfather went into that joke.
