The Boat - Buster Keaton
Buster's handmade boat, The Damfino, is finished and is, of course, too large to get through the basement door. When he drives off with it in tow, the side of his house, then the whole thing, collapses. At the harbor he rides the boat out only to have it sink beneath him. The rest is a series of adventures he and his family have with the restored boat.
