Johnny's freeloading brother Henry will go to any length to bet on a tip at Belmont, including stealing from Junior's piggy bank. When Johnny's mother-in-law tells them to take Junior to the dentist to have a tooth pulled, and gives them $2 for the doctor, the game is afoot. The money goes to Henry's bookie, and the boys decide to pull Junior's tooth themselves... by tying a string onto the back bumper of a car. But a pet parrot spills the beans, and mother-in-law goes chasing after them with fire in her eye, and a fireplace poker under her coat.
