Naked Gun
Thanks mate.Still laugh at that even from 20+ years ago.
As the pilots on here will probably know, planes like the Cessna 172 do have a dipstick in the engine!Has to be those two. So many visual puns , you nearly see a new one every time you watch it. A couple of my faves;
Robert Stack (Captain Kramer) whipping off his sunglasses, only to reveal another pair underneath.
The black guy trying to close "the bonnet" on the plane and being catapulted into mid air.
The kid in the control tower crashing the plane by using the instruments as some sort of arcade game.
