Higher Than A Kite (1943)

The Stooges join the RAF hoping to fly, but wind up as motor pool mechanics instead. After they destroy a Colonel's car, they hide in a "sewer pipe" which is actually a blockbuster bomb being loaded onto a plane. After the bomb is dropped behind enemy lines, Moe and Curly disguise themselves as German soldiers, while Larry dresses as a seductive (?) senorita. Marshal Boring falls for Larry in drag, as the Stooges plot to steal the Germans' war plans.
