There was another one which omitted the `not` in the 10th commandment, so it read `Thou shalt commit adultery`
Wow, I feel like an idiot...I had no idea that Discworld was part of a novel series. I always thought it was just the movies. Which I love, by the way. I'll definitely have to start reading those!
