What's interesting is that the screen cap of the youtube vid, is different from the actual pie. It's from a different angle. It might be the same pieing from a different angle, or it might be a different pieing altogether. I'm honestly not sure!
Eagle-eyed viewers whose eyes are younger than 42 and whose eyeglasses are less dirty than mine, what say you?
This is called knowing how to sell the video. The person started from the assumption that a pie in the face would attract the public. He probably redid the scene in more detail to get the shot.
