Bart begins designing T-shirt slogans, and his T-shirts become very popular among the citizens of Springfield.
Bart becomes famous designing T-shirts and is taken in hand by shifty salesman Goose Gladwell. With Bart a success Homer decides to spend more time with Lisa and steals plutonium from the power plant to ensure her model of a nuclear reactor wins the school science fair. Lisa is horrified but the model comes in handy after all as Homer threatens to detonate it unless Goose Gladwell gives Bart the money he owes him.—don @ minifie-1
