Sherman Oaks Is A Rat. Sherman is so spoiled and rich that he threw away his allowance because some of the hundred-dollar bills were wrinkled! He and his goody-goody friends and Nyce House are always trying to get Bernie Bridges and his Rotten House buddies into trouble. Well Bernie's in big trouble now. Bernie has a dog in his room, Sherman know it -- and there are NO PETS ALLOWED at Rotten School! Bernie has to find a way to hide Gassy, his dog. But the dog stinks. Hey, why do you think they call him Gassy?
