Professor Frink's new invention shows Bart and Lisa their lives in eight years time. Whilst she is on a Burns scholarship to Yale,he lives an aimless life and his girl-friend Jenda dumps him. To win her back he takes a job at the Kwik-E-Mart,saving Burns from being robbed by Snake. The grateful old man gives Lisa's scholarship to him but,seeing that Lisa is now doomed to a boring marriage to Milhouse,he gives it back to her. Marge,meanwhile,dumps Homer for Krusty but not for long.
