I'm a new fan of Seinfeld, didn't watch it when it first aired, recently bought the complete series box set. Now this episode was one of the reasons I bought it, what a great episode absolutely hilarious!
George buys Elaine a "new" cashmere sweater after she gets him a job for $85 that has a red dot on it and it just takes off from there, really well written.
One of the highlights would be when Kramer swings open Jerry's door and he's standing just a few paces away from it, the expression on his face is priceless...
Definately one of my favourite episodes of season 3.
