This is one of the "fake Shemp" shorts, aka the Stooges owed four shorts to Columbia with Shemp when Shemp passed away. So those four shorts are remakes of earlier Shemp shorts with some new footage of Moe, Larry, and a "fake Shemp" who usually has his back to the camera and leaves the scenes he's in very quickly. This one is a remake of Fuelin' Around. They change the story a bit so the Three Stooges are spies sent to steal the rocket formula unlike the original where they're just.regular guys who get caught up in mistaken identity and espionage (aka Larry is mistaken for a professor with a formula for rocket fuel). This remake, like all the "fake Shemp" remakes, is kind of pointless, but a new scene where 2 beautiful spies put the boys in their place for being fresh is hysterical and makes the short worth watching.
