For overall flow and plot continuity, I'd say the Feb. 20 episode was the best written this year. All the storylines merged, even Elaine's and George's (when jackhammering George tips his hat to janitor Elaine). I thought the Chicken Roasters episode was funny, but the last five minutes of 2/20 was the funniest stuff I've seen on "Seinfeld" in the last five years.
Seeing Newman burn in his mail van after singing "Three Times A Lady" was sick, but hilarious. Thank God they didn't kill *him* off!
