==============================
"David After Dentist" (2009): A viral video featuring a 7-year-old boy who had just gone through a dental procedure and is feeling the effects of the anesthesia. The video is 3 minutes and 19 seconds long, but it has a 14-minute version.
"The Slow Mo Guy" (2011): An extreme sports video featuring a guy doing various stunts in slow motion. This video is over 14 minutes long.
"PewDiePie's YouTube Rewind" (2017): A video by popular YouTuber PewDiePie that is a commentary on the 2017 YouTube Rewind video. This video is 14 minutes and 11 seconds long.
However, it's possible that you're thinking of a different video. If you can provide more context or information about the video, I'd be happy to try and help you identify it.
