I fixed a few things.

Have the patience to make it through the first 2 and a half minutes. If the next section bores you, jump to 5:30. If that bores you, give up. Click full screen to read the subtitles, and if you watch the whole thing be warned that later the subtitles conflict with the audio.

I don't know why I'd assume people get the jokes, but the piece is meaningless without them.
