Two man were having a large party and all the rooms and floors were messed up. They had to clean up because one of the man's parents were coming but they don't have much time left.Then the man with the beard told the other man how to clean and polish by using banana skins so they used banana skins to clean all over the house. In the end, they were managed to finish it before the time.
At first, I thought they were brothers but I noticed that they aren't in the middle of the film because there was a memo "party" on the calender and at the end they were waving hands.
I think the man with the beard loves banana and he thought that the banana skins can use for something instead of wasting them.
I think this film is saying that banana skins can use to clean many things in many ways and it is really good to reuse things.
