This was a funny YouTube video shown to me by a friend. The video shows a husky following along as a baby whines and utters incomprehensible sounds right next to it. The video is almost 3 minutes long, all of it the same repetitive husky-copies-baby scenario.
I did not watch the entire video, but I almost did. The video was indeed hilarious, but I wondered why I was glued to watching the same, repetitive thing for more than 2 minutes. One simple explanation would be that, simply, it was funny. Seeing the same hilarious scene over and over again was probably satisfying and engaging for me as a viewer. Perhaps another reason though was anticipation of something even funnier or cooler. For every time the husky howled with a funny sound, I wondered if later on in the video the husky would make an even funnier sound right next to the baby.
I realized that perhaps, it is this sense of anticipation that makes videos without clear plots successful. Because the video has no clear trajectory, the viewer does not know when the video will reach a pinnacle in which the scene is the funniest or most engaging. Thus, the viewer keeps watching the same repetitive scenario. However, this only works after some time. As I did, most viewers probably realize shortly that there is not much else to the video like this, hilarious as it may be.
