The Know-It-All: One Man's Humble Quest to Become the Smartest Person in the World (Abridged Edition)
Humorous and informative. Lots of "Huh! What do ya know?!" moments. I would not put this up there as being as humorous as Bill Bryson's works, especially A Walk in the Woods: Rediscovering America on the Appalachian Trail, but certainly as informative as his works. The narrator on this audiobook was great--very enjoyable narration style.
