I've seen some of these videos, but I've also missed a lot of them. The interesting thing (to me, anyway) is that while I probably wouldn't watch an entire video of skate boarding or parkour or bungee jumping or anything like that, I was fascinated when only the best one second (or so) of those types of videos was interspersed with the best one second of animal videos, underwater videos, baby videos and others. Fun stuff. Even better, the compilation artist Zapatou (Luc Bergeron), included links to all the videos (check the numbers in the bottom right corner of each clip). If you see a clip you like, you can check out the entire video.
