Hats Off! is a Laurel & Hardy silent short film released 5 November 1927. No copies of this film are known to exist. It was remade as 1932's The Music Box, and again as 1945's It's Your Move, starring Edgar Kennedy.
Stan and Ollie are salesmen trying to sell a washing machine, but they fail repeatedly. Them carry the machine up a large flight of steps to a prospective buyer, only to find out that the young lady wants them to post a letter for her. The boys later get into an argument knocking off each other's hats, which eventually involves scores of others. A police van eventually carts all those involved away except Stan and Ollie, who afterwards try to find their own hats among the hundreds of others lying in the street.
