I believe either Tosh.O or Wacked Out Videos showed it one day...I'd have to doublecheck. Apparently the video has the poking and what not going on for awhile, until he finally stands up and punches the other kid in his face lol.
I don't know if there is a video afloat of the .gif or not lol... I just so happened to stumble across this gif while perusing the interwebz. I would love to see the video as well. If you ever find it, tell me please :P Likewise if I ever find it.
