Jerry's parents sell the Cadillac to Jack Klompus for $6000 in order to give Jerry some money to help him out.  They along with Kramer suggest that Jerry might try a career move.  Elaine talks about her Peterman stock options and buys George's coffee.  He thinks she is sticking it to him.  Jerry and George talk about the money their parents might have.  This piques George's interest.  Kramer seeks advice from Elaine about his girlfriend's post-sex bed habit "she's got the jimmy legs."  Jerry flies to Florida to buy the Cadillac back.  George seeks information on his family's health history.  Kramer works out a deal with his girlfriend.  Jerry meets with Klompus and agrees to pay $14,000 for it.  George anticipating a big inheritance begins to spend money.  Unfortunately for him, so do his parents.  Klompus has a problem with the car and Jerry returns to Florida.  Jerry's parents are still worried about him and wonder what to do.  Morty decides to see Elaine about a job; she reluctantly agrees to give him a job, just as Peterman returns.  Kramer, fearing a prowler (Jerry's dad), decides he can no longer sleep alone; unfortunately his girlfriend has decided she can.  So he moves in with the Costanzas, who tell George that they are moving to Florida.  Elaine returns to her regular position at Peterman, with no options.  George and Elaine try to discuss their respective problems.  Still in Florida, strapped for cash and credit, Jerry sleeps in the Cadillac.  Kramer and Emily spend the night as an old married couple in the Costanzas' house.  The Seinfelds make a change in their housing as the Costanzas try to settle into their new place.

This is just the kind of amusingly off-center comedy now missing from NBC's lineup, one of those rare, delightful meshings of concept, cast and execution, with producer Tom Cherones providing inspired direction.  Nothing is forced. [ 31 May 1990, p.F9]

The weakest aspect of Seinfeld is a wacky next-door neighbor played by Michael Richards.  Richards is doing little more than an impersonation of Christopher Lloyd's Jim on Taxi, and he ought to cut it out.

One weak link is fellow stand-up comic Michael Richards as Seinfeld's wacky neighbor.  He isn't wacky or neighborly enough; it just doesn't work.  But he's in the minority where "Seinfeld" is concerned.  You may not convulsively guffaw, but you're bound to convincingly smile.  Here's one that worked out just right.

There are some who might be jarred by the format, seamless as it is.  And still others might be compelled to argue that with this format one gets neither a sitcom nor a comedy show, but insufficient portions of each...But there is an intriguing honesty to this method, and, in its fashion, it shows how life's tiny travail can work its way into comedy club laughs. [ 31 May 1990, p.C4]

Matt Roush

Lacking much in the way of attitude, the show seems obsolete and irrelevant.  What it boils down to is that Seinfeld, likable as he may be, is a mayonnaise clown in a world that requires a little horseradish. [ 31 May 1990, p.3D]
