Let's Get Married (1926)

College football star Billy Dexter is prone to getting into public fights. His father demands he reform and sends him to mend his ways with a devout old woman who deals in hymnals. She turns out to be devoutly drunk and a saloon brawler, leading to Billy's imprisonment. He tells his fiancée he's doing missionary work on a pacific island. He escapes and persuades her to marry him, all the while dodging the police who pursue him.
