I absolutely loathe a great majority of the post-Larry David episodes of Seinfeld, and "The Chicken Roaster" is one of them. It's funny, yes, but it's NOT the same brand of humor that the show is known for in it's first five or so seasons. Although, I must admit that the episode DID show some very interesting hints of creativity -- most notably when Jerry and Kramer switch apartments/personalities; and Kramer's whole boycott of Kenny Rodgers Roasters was pretty funny, too. So... I'd actually have to say that the episode was at the very least an original work, I'll give it that. But God, I simply couldn't stand watching the later years of this damn show.

You also mentioned the episode where the Japanese guys sleep in Kramer's chest-of-drawers; again, horrendous in my opinion. Although, again, it had it's moments -- such as the 'potty-mouth' executives from the Houston Astros. Those scenes had me cracking up, but on a very superficial and shallow level. It was NOT on par with the level of humor that helped establish the show as such a unique and original work of art..
