This episode was silly, strange, and about Sneakers!
It shouldn't have worked, but it did. Hilarious interactions between the regular cast, an interesting plot that had all sorts of twists and turns. I even found the math interesting -- the voice recognition software and the laser machine thing were both cool concepts.
The best thing about this episode was all the information we learn about our favourite characters -- how they interact, how they see the world, what brings them together and what they differ on. It's an episode I rewatch often, mostly for all the self-mocking humour. It's like everyone but the crazy sneakerheads are in on the joke.
