All In The Family

I've noted these days each episode of The Simpsons seems to be a composite of older episodes. Hard not to repeat yourself after 400 episodes.  Or 200.  Or 100.

Family Guy has done over 150 episodes, and the latest, "The Hand That Rocks The Wheelchair," so clearly calls back to former plots that characters on the show commented on it.  The main plot has Meg go psycho, obsessing over someone who doesn't love her back.  The other plot has Stewie create an evil version of himself--not unlike the old Stewie--who goes on a killing spree.

So neither plot was particularly original.  Odder still was that both were similar.  If you're gonna repeat yourself, try to steal a B-plot that's different from the A.
