Video: Wizard of OZ Suicide

The rumored munchkin suicide by hanging in Wizard of OZ is not true, from Snope

The so-called "munchkin suicide" scene occurs at the very end of the Tin Woodsman sequence, as Dorothy, the Scarecrow, and the Tin Woodsman head down the road on their way to the Emerald City. This sequence begins with Dorothy and the Scarecrow trying to pick fruit from the talking apple trees, encompasses their discovery of the rusted tin man and their encounter with the Wicked Witch of the West (who tries to set the Scarecrow on fire), and ends with the trio heading off to Oz in search of the Wizard. To give the indoor set used in this sequence a more "outdoors" feel, several birds of various sizes were borrowed from the Los Angeles Zoo and allowed to roam the set. (A peacock, for example, can be seen wandering around just outside the Tin Woodsman's shack while Dorothy and the Scarecrow attempt to revive him with oil.) At the very end of this sequence, as the three main characters move down the road and away from the camera, one of the larger birds (often said to be an emu, but more probably a crane) standing at the back of the set moves around and spreads its wings. No munchkin, no hanging — just a big bird.
