A Walk in the Woods: Rediscovering America on the Appalachian Trail
By Bill Bryson
Bryson and an estranged and strange college chum decide to hike the Appalachian Trail...in their 40s without almost no physical preparation. If that's not humorous enough, the picture of the bear on the cover is connected to a passage in the book guaranteed to generate snorts for years to come.
