Reading Usable Help

Stuntology by Sam Bartlett is not the kind of book you'd expect to see referenced here on Usable Help, but that's exactly why I'm calling it out. It's a fun and fascinating collection of stunts and gags, such as proving that you have an extra middle finger or balancing a can of soda on its edge, but beneath the humor it is a study in folk instructional design.
As you can see from the sample pages at Amazon, each stunt is described in a single page with charming illustrations and writing. It's really quite fun and compelling, and when was the last time you found a manual like that?
