At ROFLcon 2, The maker of "David After Dentist" (http://www.youtube.com/watch?v=txqiwrbYGrs) reported to have brought in close to six figures in YouTube revenue, just from uploading that one video of his son hopped up on nitrous. I find it crazy to believe that there's enough people out there who intentionally click on the annoying ads that interrupt the bottom of the video, but I guess when you have 106,048,879 views that's enough accidental clicks to be sufficient (?)
