The plotting of most episodes was phenomenal, that's what I liked about it. Each character would start off with their own little story or issue, and by the end of the episode they'd all come together for a hilarious payoff. The episode where George has been telling a chick he's a marine biologist and at the end has to go yank a golf ball out of a whale's blow hole that Kramer had hit in to it is a perfect example.
Yeah I was going to post exactly this, you're not going to "get" Seinfeld if you've never watched a full episode.
Start with Sopranos, Deadwood or Rome. These three shows do an excellent mix of episodic excitement, and long term story telling--as well as amazing acting and deep story lines. The big thing is though that you'll see dividends, in terms of story, in the first episode. The Wire, Breaking Bad, Mad Men and Boardwalk are just as good, BUT they take a few episodes to put out and they are long burns--which means entire episodes can be set ups for future stories (NOT filler, just no real "satisfaction" that something happened.).....If you're not into TV, these shows can lose you before you really get anywhere (Many a people never get through season BB--which sucks because the long story is mind blowing good.)
Rome is actually shorter than Deadwood, if that is your concern with starting.
