The funnymooners (1926)

Ralph attempts to elope with Thelma against her parents' wishes. Ralph disguises as a teacher to take her off to a boarding school and there is a new and amusing gag where he gradually discards his disguise while walking along the street. Marvin, an insurance agent, fastens himself on to the young couple and succeeds in muddling things up generally, finally insisting on taking them to a hotel and sharing a room with his wife. Ralph gets around this embarrassing situation by getting the insurance man in his bed to talk business with him. The girl's father appears the next morning and Ralph is tickled when he insists that they get married, but the pest almost queers matters by phoning to the justice of the peace that his house is on fire and his wife murdered.
