Amigurumi Bender from Futurama
You might remember MNC's earlier work as I featured her Brain Slug in my How to Make an Alien Parasite article a while back. Sadly there's no pattern for Bender, but there is are plenty of other brilliant geeky free crochet patterns including a crochet pattern for Zoidberg, along with a pattern for the worm from Labyrinth.
In short Most Nerdy Crochet is a well worth keeping your peepers on for more geek craft. And if you don't like it you can "Bite my yarny crochted ass!" as crocheted Bender would no doubt tell us.
