I once saw this episode of Mad About You where Paul and Jamie* get into a fight with another couple over a cab, and the other couple were on their way to see Cats, and Jamie snaps, "Cats has been out for fifteen years and you haven't seen it yet?!"
I think about this whenever I see someone reading a David Sedaris book on the El.
Coincidentally, has David Sedaris entered the same lame collective consciousness of Cats and Mad About You in the sense that he's now so popular and a mainstay of funny little personal essays that he appeals to the lowest common denominator? Could one compare his career to that of the greatly underrated Paul Reiser? I'm sure someone must think that.
*To be clear, I had to look up their characters' names on IMDb, because I never watched Mad About You because that show sucked.
