Porky's Super Service (1937)

Porky owns a full-service gas station; he deals with a wide variety of problems, like a bump that migrates to different parts of the car. But his real nemesis is a supposedly sleeping baby in a car whose tire needs changing; in fact, the baby is wide awake and a real brat. Both Porky and the brat end up covered in grease; the irate mother drives off, but the child has tied a pump to a tire, which ends up pulling the whole station into the ground.
