I was just thinking about this episode a couple days ago. To wit, how much I didn't like it.
Most of my favorite shows eventually have what I call an "experimental episode" that is devoid of most of the stuff that makes the show enjoyable.
Other examples: Breaking Bad's "The Fly" episode, and "The Sopranos" when those two guys spent the night stranded in a car in the woods.
Back to Seinfeld: I do often use the word "urimiciticis" from the episode, so it wasn't all bad.
