Well, I have no proof it was made by JW's, it is circulating amoung witnesses I know as made by brothers. I can't think of anyone else except for JW's who could capture so perfectly the mindset of the average dub towards service and the people they meet in the ministry.
As for the second point, I never claimed the society approved it. There have been quite a few cases where artistic dubs, musicians, etc, have taken it upon themselves to do something creative that they think will have a positive effect on people who see it, only to be slammed by the society afterwards for showing independence in doing their own thing without watchtower approval. I'm sure when this video gets to the right PO, CO, DO and on to bethel it will be yanked post haste!
