Wasn't there an original 1930s/40s episode of 'Blondie and Dagwood' where a salesman is demonstrating in their home, and selling them a bolt down washer, but it isn't bolted down because they didn't buy it yet? The salesperson had it on wash and told her not to change the dial because it wasn't bolted down. She gets distracted by Baby dumpling and the dog and turns the machine to spin and it moves all over the kitchen.
