Paul McCartney’s one condition he demanded when he guest-starred on The Simpsons

Sir Paul McCartney and his wife, Linda, both guest-voiced a Simpsons episode in 1997. The former Beatle and his wife only had one demand: Lisa, who was always an on again/off again vegetarian on the show. But after they were guests, the McCartneys demanded Lisa must remain a vegetarian in all future Simpsons episodes. Their request was granted.
