Buster Keaton: Lovenest 1923
Buster bids farewell to his girlfriend and sets out on a small boat. Later, without any food or water, he is taken on board the Love Nest, managed by a despotic captain. Making his escape, he encounters a large flotation device which he does not recognize as a target for nautical maneuvers. It is blown to smithereens. Suddenly Buster realizes that it was all a dream and to his consternation, discovers that his small boat has never left dock.
