Out on a Limb is a 1950 Walt Disney Animation Studios short featuring Donald Duck and Chip 'n' Dale.
He climbs a ladder, cuts a branch and puts tar on it, when an acorn falls on his beak.
Donald eventually ends up getting an electric shock on the high-voltage wires and falls on the leaves.
Chip 'n' Dale then put the tar on Donald, causing him to turn into a "leaf monster", and the chipmunks laugh in triumph, only to accidentally get their tar-covered hands glued together.
The short was released on December 11, 2007, on Walt Disney Treasures: The Chronological Donald, Volume Three: 1947-1950.
