S17E07 The Last of the Red Hat Mamas
Marge meets up with a sorority called the Cheery Red Tomatoes,who wear red hats and with whom she has a great time hanging out. However it turns out that some years earlier Mr. Burns reneged on a promise to give them a charity cheque and they mean to get even by robbing him of the Faberge eggs in his safe. Reluctantly Marge goes along with them and, even though they are caught,manages to sneak out one egg by keeping her hair on. Lisa,meanwhile,is charmed when Millhouse woos her in Italian.
