Set your DVRs, Cortexifans! Starting Tuesday, Nov. 20 at 8/7c, Science Channel will begin airing repeats of Fringe from the very beginning, starting with 2008's bangin' two-hour pilot that introduced us to Peter, Liv and Walter, followed by the second episode.

And because it's Thanksgiving week, the nerdy-cool network is giving us even more reasons to be grateful: day-long marathons of the show on both Friday and Saturday, running from 10:30am/9:30c to 11pm/10c, as well as "Science of Fringe" shorts slated to run during the regular airings every Tuesday night starting Nov. 27. As Walter would say, how delightful!

So stock up on Red Vines and get set to go back to a simpler time when the Observers weren't so mean and the Pattern was all the rage. If you can't wait for the reruns to fire up, here's a sneak peek at one of the "Science of Fringe" pieces to tide you over (and freak you out).
