History
Bart and Lisa decide to tour it. At the top of a mountain, the two discover Martin excavating for arrowheads. While Lisa joins him in excavating, a frustrated Bart decides to play a prank on Martin. He steals Sideshow Mel's bone (which causes his hair to fall down, revealing it to be long and straight), and partially buries it in the ground for Martin to find. Martin arrives and thinks it is a real historic bone, and Bart tugs on a string connected to the bone, which causes the bone to fly up and knock Martin in the head. A stunned Martin tumbles over the edge of the cliff, and falls onto a smaller ledge. Lisa, trying to help him, taps him with a stick, which causes Martin to fall off the ledge and to the very bottom. Shocked at what happened, they presume him to be dead.
