Without question, one of the best pure Seinfeld episodes. From the bra discussion, to George's interview, to the discussion of drugs, just an all out classic episode. Jake was hilarious in this appearance, "I'm leaving!" and this was one of George's best outings.
Season 5 was when many people felt that Seinfeld had its stride and it would be hard to argue against that point having seen this episode.
As I mentioned that job interview scene was one of the all-time greats on this show and is something that any fan of comedy should watch many times and have it memorized.
