There are two main characters. One person lives in the house and is freaking out about his parents visiting at 12:30. At 12:30, the man was going to receive a visit from his parents. The
problem is, the man seems to have forgotten all about it, and had a
crazy party the night before. The house is a mess, and the man has to
clean it all up before his parents come.
The other is a man with long hair. He seems to be a visitor or a friend of the man who lives in the house, because he isn't flustered like the other man. The man with the beard is the one who teaches the poor owner of the room how to clean his house using overripe bananas.
In the end, thanks to the man with the long hair, the house is cleaned up, and everything is ready for the parents' visit.
I'm guessing that the bearded man was so knowledgeable about bananas because he went to an Earth Day festival and was shocked at how much bananas were being wasted. So, after that he researched a lot about bananas and how to use them.
