There is no doubt that a lot of people do a lot of stupid things on YouTube. That's not to say that there aren't tens of thousands of educational and highly intelligent videos on YouTube, but, keeping it real, there is also a ton of really stupid stuff posted to the world's largest video sharing website. A fairly large category of videos that would be considered pure junk are the popular "Challenge" videos. These videos feature YouTubers performing various challenges for the entertainment of viewers. Some of these videos accumulate a lot of views, especially if the challenge is particularly difficult or if something interesting transpires during the course of the video. Popular challenges include those listed in the song featured on this page and many more. So, if you don't have any good ideas, but want to post a video, then you might consider one of the many amusing and entertaining challenges for your next video!
