In 2012 The Simpsons closed out their 23rd Season by bringing in pop sensation Lady Gaga. The plot saw Gaga somehow telepathically sense Lisa Simpson's depression and so she headed to Springfield to cheer the 8 year old up. And that's about it. Lady Gaga, to her credit, willingly parodied herself with good humor, but she was all over this episode and most of the jokes weren't funny. The Simpsons have often been criticized for wasting celebrity guest stars in one off segments that have no bearing on the story. Well here we got a whole episode revolving around the eccentric singer and it fell pretty flat. So much focus was put on Gaga that the Simpsons felt like secondary characters on their own show!
