I will explain my own downvotes, I don't claim to speak for the others.

I saw the first comment as an uncalled for attack on the poster, and not an attempt at humour. The other comments I downvoted because they were both unrelated to the video, and mean spirited. Had they been on a talk page, or on a profile page, I would probably have kept out of it.

If the original comment was an attempt at humour, then it wasn't terribly funny in any case... and the timing was terrible.
