Mickey's Service Station.Mickey Mouse, Donald Duck and Goofy are working at a car service station, working together to fix a broken car. Soon Peg-Leg Pete comes by, and angrily demands that they fix a squeak (to the tune of "Yankee Doodle") in his tire. He tells them that if they don't get the job done in ten minutes, they'll have their heads cut off. Scared by the thought, they quickly get to work. Slight gags show them to be inept at car repairing, including scenes where Goofy and Donald pull each other through the car's lights, Mickey getting stuck in a tire several times, and Goofy smashing pieces of the car's engine. Finally Mickey is able to squeeze a tire and pop out what was making the noise: a grasshopper. The trio smash several pieces of the car with hammers before Mickey is able to drive away the grasshopper. They then get to the job of repairing the car, noticing that their ten minutes are almost up. They are better at repairing the car, though Donald gets accidentally injured a few times and Mickey gets himself stuck in the tire again. When they finally finish the job, Mickey gets in the driver's seat and tests the engine, but Goofy accidentally hits a lever making the stand the car is on go up. Goofy saves the car and Mickey from crashing by making the stand's base land in Goofy's shirt...
