It’s easy to see why Jerry Seinfeld took an extended break from television, as Seinfeld is one of the medium’s most iconic programs. The show about nothing had a profound impact on the pop culture landscape, and over a decade later the comedian is producing the new show The Marriage Ref.  The reality series, which helps married couples sort out their problems with the help of panelists and host Tom Papa, airs tonight on NBC at 10 pm et/pt.  Seinfeld, who played himself on the recent season of Curb Your Enthusiasm, talks about returning to television.
