Alike and Different - S3.E6

"Beauty and the Beast", in a town called Splitsville, there lived two groups of people, the Beauties, who wear only polka-dots, and the Beasties, who only wear stripes. Both groups did everything opposite from one another, when one group went forward, the other group would go backwards. Until one day their cleaners got their clothes mixed up and found out that both groups have things in common with each other.
