Jim Baker's BlueJay Yarn by Mark Twain-When Mark Twain stayed in a California gold camp in 1864-65 he picked up a lot of story ideas.  With his unique brand of humor, he manages to compare the labors of men digging things out of empty holes to the labors of a blue jay filling a knothole in the top of an empty house with acorns and not unfderstanding why he couldn't fill it.
