There have been a few parody cults in media, most recently with the Taco Bell "Belluminati" promotion. I think there was one with Sprite a few years ago called "Sublymonal", but my first experience with a fake product placement cult was The Order of the Serpentine way back in 2006.
The Order was formed around the thesis of "THE WALK OF SHAME ENDS HERE", and by using Axe Snake Peel body wash, you could be reborn by washing away your awful hook-up decisions. Personally, I think the musclebound lady on the pamphlet is very attractive, but this is supposed to be propaganda I guess so I don't want to think too much about what their message is.
So from what I can remember, there was a website set up where you could receive coupons to buy Axe products and be part of a mailing list. So I signed up, thinking nothing of it (which is probably how most cults function anyway) and left it at that. A few weeks later a package arrived in a plain brown envelope and my initiation was done.
The kit contained all the items seen below (a pamphlet, a membership card/certificate of acceptance, and a really uncomfortable wristband), but there were also small sample packets of the Snake Peel body wash included, which I of course used.
And that's really it. I believe the official website had like desktop wallpapers and maybe a novelty screensaver, but I don't remember too well. I just wanted some coupons and free samples, and I ended up with a full initiation kit. The promotions didn't last for too long. I'm sure there are conspiracy theorists who look down on this like they do on the Belluminati stuff, but I think it's fun. Definitely not to be taken too seriously.
I guess I'll go out and by some Snake Peel now. It's been a while since my last Daily Scrubbing Ritual.
