The video: how to use a banana in seven unexpected ways

The apartman guy wants to clean up his room immediately, because his parents visit his room the day. However, his room is very messy because of the party of the previous day. Suddenly, the man who attend the party of the previous day wakes up and explains to clean up his room by a banana. Most of ways are useful for cleaning, but some way is not useful for cleaning. For example, a banana heals itching. It is unexpected way to use a banana, but it's not important in the situation. So, I think it's irony. The banana master want to teach him how to clean up his room with a banana, but he also tell the apartman guy unuseful information in the situation. I think his room wouldn't clean up by the time when his parents visit there.
