Diners in the US found themselves floating downstream inside a restaurant.
A total of 83 visitors and staff had to be rescued when the Waterfront establishment broke from its moorings on Ohio river and travelled 100 feet.
They were rescued one by one with a makeshift gangplank of ladders and ropes once the boat restaurant came to a rest down the river.
Customer Kathy Kinane said: "We were joking about the river. Well, the joke's on us now."
