His Wedding Night is a 1917 American two-reel silent comedy film written, directed by, and starring Roscoe "Fatty" Arbuckle.

[2] Arbuckle portrays a lazy and dishonest store clerk who gets into various slap-stick situations, such as drugging customers with chloroform-laced perfume and tussling with a donkey.

Later, in a ploy to kidnap Alice and force her to marry him, he accidentally rides off with the delivery boy (Buster Keaton).

Unaware of the mix-up, Arbuckle attempts to rescue her, nearly paying a justice of the peace to wed him to Keaton in the process.

The film concludes with Arbuckle marrying Alice, then drugging the justice of the peace with the chloroform-laced perfume to recover his money.
