Seriously, she’s bringing the egg (er, vessel) — along with 18 different costumes and who knows what else — to the season finale of Fox’s The Simpsons. How exactly does the monster pop star wind up in town? When Lisa’s scheme to boost her popularity at school goes horribly wrong, Gaga, who happens to be chugging past Springfield on the Gaga Express, magically intuits that her help is needed. She’s determined to cheer up Lisa — and the rest of Springfield — by all means necessary, including through song and flash mob. In this clip from the episode, you will see that Lisa isn’t exactly going gaga for Gaga, and that hurts Gaga’s feelings. And when Gaga’s feelings get hurt, something priceless happens.
