Has anyone seen the funny 1980s movie “The Gods Must be Crazy?” There’s a scene where a band of African revolutionaries are trying to bring down a helicopter by firing a bazooka at it. The only problem is that the round keeps falling out the back side of the bazooka. After numerous attempts, some bright bulb solves the problem by stuffing a bunch of banana leaves up the back side of the bazooka. The weapon is fired and the helicopter comes down.
This was found to be a very good movie. A very long journey to toss an empty cola bottle off a cliff. Seen years ago and seen more than once (IIRC)
