This episode is a brilliant example of everything I watched Futurama for. From their skewering of not only Christmas, but other holidays ("What the Hell is Kwanza?", anyone?), to Bender's screwy dialogue, to the Robot Devil's cameo and the nutty courtroom scene, this is the sort of episode that keeps me laughing from the first frame to the last.
Futurama's Christmas is so bizarre, so utterly removed from our own that watching these episodes is barely like watching a Christmas episode at all. And as much as I love Christmas and everything that comes along with it, I can't help but smile at the insanity that Groening and company managed to whip up.
