The Simpsons - 17x15 - Homer Simpson, This is Your Wife

    Homer is enraptured by Lenny's new HDTV.  In an effort to get enough money to replace the family TV, Homer winds up winning a tour, which eventually lands the family on a reality TV show, where Marge and another mother swap families.  The man she's paired with develops a crush on her.
    I like Ricky Gervais quite a bit.  I loved the original The Office.  His type of humor doesn't blend evenly with The Simpsons.  It's not a terrible episode, but it still isn't really right.  Plus, there's a similar premise already used - back in the 14th season, with Helter Shelter, when they do a reality TV show called the 1895 Challenge.
