When I first received a Gideon (looked up the spelling, haha) from a random stranger in a suit outside my high school as a teenager. I, of course, rushed home to eagerly spend my evening reading the Holy Book, only to discover it only contained the New Testament, what a gyp. I think it's a marketing ploy to try and get you to go out and buy the complete thing.
My favorite religious group is still the Raelians, with their cloning hoaxes and weird UFO village cult headquarters. They're off their rocker, but it's hard to dislike a group that just wants to hang out talking about aliens and having orgies.
