Yin! Yang! Yo! Sezon 1 Odcinek 21: Attack of the Lesson / A Case of Evils

Attack of the Lesson: When Yin and Yang accidentally release "The Two Bad Habits" - Eats2Much and Duzznt Exercise - they accidentally summon the puffy-chested self-important superhero... "The Lesson!" A walking talking "School House Rock" with a mean streak, he sings, dances and hammers his message into the heads of children! Can Yin and Yang learn the lesson... and then defeat him? / A Case of the Evils: When Master Yo accidentally drinks a little of Carl the Evil Cockroach's backwash, he catches a "Case of the Evils." And when the last Woo Foo master on the planet goes bad, that ain't good! Yin and Yang have to use all their skills - and every weapon in the armory - to try to take Master Yo down!
