Don Donald (1937)
"The first official Donald Duck cartoon"
Donald is courting Daisy (called Donna, here in her first appearance) Duck in Mexico. He arrives on a burro, which doesn't get along at all well with her; she convinces him to buy a car. They head through the desert, but the car breaks down, and throws Donald out, then takes off on its own with Daisy trapped inside the rumble seat. The car hits a rock, throwing Daisy into a mud puddle, to Donald's excessive amusement. Daisy pulls a unicycle from her purse, and rides off.
