They Stooge To Conga (1943)

The Stooges are fix-it men who are employed to fix the doorbell in a house that belongs to a nest of German and Japanese spies. Moe, Larry and Curly proceed to destroy the walls of the house looking for the problem before moving outside. Curly is then sent up to fix the wires atop a telephone pole. While "fixing" the lines, Curly slides his chair towards the window of the spies' main control room and crash through the window inside. He discovers their sabotage plans and he, with Moe and Larry manage to sabotage the saboteurs and get the final drop on the spies.
