Part of the 50m views came from ABC News reporting it on their site. I think it's great that an innocent, fun video took off like that, rather than some tragedy or keystone-cop video. I think the "School's Closed" videos have had their 15 minutes of fame. They were fun but overdone.
There's a skatingboarding TRex video, but I can't tell if it was done by the same crew. The boarder is good, nothing too fancy, and he doesn't crush his tail. The best part is the music - it's the theme from Jurassic Park! lol
