Adult Swim has been kind enough to put up the special episode up on their site
and it doesn't look like it requires a cable provider login of any sort. So if you couldn't watch it tonight, or want to watch it again, here's a way to do that. The online version also includes the epilogue tacked onto the end, so you won't even need to hunt that down in the aftermath. And don't forget to join in on the discussion here
after you watch it!
