When I was researching to try and help my wife 'escape' (which failed miserably), this was one of the funnies things I found . . .

It's an article on the Witnesses' demonization of aluminum with lots of good pictures. Some of the Golden Age cartoons were pretty good . . .
The funny thing is that I was working for Alcoa, the largest aluminum company at the time and my wife was saying what a good job was. I guess she didn't realize that aluminum was Satan's metal only fifty years ago . . .
