The Mail Fraud, the episode that really showed me why Seinfeld is far and away the greatest sitcom of all time. This was a true situational comedy, something the show wasn't always, as all the storylines ended up costing everybody royally in the end. You really did not have a dull moment in the broadcast, and as far as Newman performances go, this has to be one of his best.
"It's pretty hot under these lights, huh, Seinfeld?" "Actually, I'm quite comfortable." Just a brilliant exchange and proof that these later episodes of Seinfeld still had some mojo, despite not holding up with all the old ones.
