Hello Lafayette (1927)

A salmon taster enlists and is put to work passing out salmon to the troops. When he is assigned to take the salmon in the lines he gets absent minded and throws hand grenades over to the hungry buddies. With the aid of a battalion of chorus-girls dressed like Anzacs and who appear for no reason at all, the recruit captures a company of Germans and is decorated by the Colonel.
