Buster Keaton in The Scarecrow (1920)

Buster plays a farmhand who competes with his housemate (Roberts) to win the love of the farmer's daughter (Sybil Seely). Running from a dog that he believes is rabid, he races around brick walls, jumps through windows, and falls into a hay thresher that rips off most of his clothes. He is forced to borrow a scarecrow's clothes in a nearby field. He then trips into a kneeling position while tying his shoes, and Sybil believes he is proposing marriage. They speed off on a motorcycle, with Joe and the farmer (played by Buster's father, Joe) in hot pursuit. Scooping up a minister during the chase, they are married on the speeding motorcycle and splash into a stream, where they are pronounced man and wife.
