Trailer Horn is a 1950 animated short film featuring Donald Duck and Chip 'n' Dale. It was produced by Walt Disney Productions and released by RKO Radio Pictures, Inc.

Plot
Chip 'n' Dale wake up one morning and go out to collect nuts but then come upon Donald Duck (who is out having a nice relaxing vacation)'s footprints and claim he has stolen their nuts, commenting thievery isn't in the constitution and plan to give him a lesson. They follow the footprints to his trailer, where they find Donald sleeping (Chip opens Donald's eye to see sheep jumping over a fence and comments "Well what do you know?" then closes it) and begin to jump on the car horn, waking Donald. Angered, he captures Dale, but Chip bites his foot and he screams in pain as they run away. They imitate the scene and laugh hysterically.

Donald comes out of his trailer wearing a swim suit and notices a diving board. Chip and Dale decide to play a trick on him and mess with the diving board, causing Donald to land onto the board and later land in his trailer, inevitably making a mess. He figures out the trick, captures the chipmunks, puts them in the horn and rapidly honks it and puts them in a pie and tosses it into a tree. Donald laughs at them before he marches back into his trailer to eat breakfast.

Chip then looks up and notices pine cones on a branch and hatches a new plan. They run up the tree and see a hole in the trailer and Donald eating his breakfast. To the tune of Stop, Look, and Listen, the chipmunks drop pine cones on his breakfast and his head. Enraged, Donald hops into his car and starts ramming the tree with it until he makes it lean like a catapult. Before Donald can tear them apart, the chipmunks hop off the tree and, realizing he's doomed, Donald funereally bids farewell before his car is thrown into a cliff and destroyed. Chip and Dale watch from the sidelines as a dazed Donald comes out of the hood with the horn in his mouth and steering wheel in his hands, behaving like a car. He honks his horn repeatedly and "drives" away toward the horizon as the cartoon ends.
