The Show-Off (1926)

Aubrey Piper (Ford Sterling), a mere clerk at the offices of the Pennsylvania Railroad, poses as an important executive to his sweetheart, Amy Fisher (Lois Wilson), by blustering, bullying, and showing off endlessly. Though all the members of her family are contemptuous of him, Amy marries him; three months later she is fully aware of his faults. To help his son Joe continue work on his invention (a rust-preventing paint), Pop Fisher gives him the money saved for the mortgage and shortly afterward dies of a stroke. Aubrey wins a Ford in a raffle and knocks down a traffic policeman while taking his prize out for a spin, and Joe is forced to pay his fine with the mortgage money. Realizing the tragedy he has brought upon Amy's family, Aubrey visits the directors of a steel company and--by bluffing--sells them Joe's invention. The Fishers are happy at last as the "show off" redeems himself.
