21x11 - The Simpsons

Homer blows off Marge to buy a lottery ticket and winds up winning the million-dollar jackpot. Fearing how Marge will react if she finds out the reason Homer missed their date, Homer keeps his newly inherited fortune a secret and spoils his family with “anonymous” gifts. When Bart finds out, he and Homer spend the money like it’s going out of style, including buying front-row to tickets to see Coldplay in concert.
