In my title I call the song 'stupid,' but this is not meant as a type of negative statement or criticism. I think that the creators of the song would have to agree: this is a really stupid song. That's why people think it's funny. The brothers from Norway who created this song deliberately (not accidentally) created the most stupid song possible to make people laugh.
Here is the video itself from youtube, where it has received almost 90 million views.
I think that, as an English teacher, I can use this video to tell you about 'onomatopoeia.' Onomatopoeia is when a word corresponds to a sound. For instance, we, in America, say that a cat goes 'meow.' Meow is the sound a cat makes. We say a dog makes the sound 'aarf!' In Korea they say a dog makes the sound 'mung!' and in China they say a dog makes the sound 'wang!' These are all examples of onomatopoeia. This song uses a lot of onomatopoeia.
Please enjoy what has to be the most stupid song and video ever!
