S19E15 Smoke on the Daughter
Homer makes his own beef jerky in the basement,only for it to be stolen by raccoons. Marge,meanwhile,wants to fulfill her childhood dream of being a ballerina and goes with Lisa to the Chazz Buzby dance academy. She is turned down but Chazz notices that Lisa has the right posture for a dancer. Unfortunately she can only dance well after inhaling the other ballerinas' cigarette smoke. Homer is appalled and has the raccoons steal all the dancers' cigarettes. At a performance of 'Sleeping Beauty' all the dancers are rubbish when deprived of their smokes and Lisa delivers a diatribe from the stage against something which is unhealthy and stunts the growth of American children - ballet.
