This is better than that incredibly awful football video, because Hart isn't always speaking at quadruple speed, and because for a brief fraction of the time it actually shows a real plane interior. But many people from all over the world will have trouble understanding him at times, and following the lengthy proceedings. The rest of us will be bored by the time of our second flight (or earlier). (I admit I quit watching the youtube video after a while.)

If the goal is to amuse and entertain, why not put such videos as options in the IFE?
