We at Geeks of Doom love Halloween. The smell in the air, the leaves changing color to mark the occasion, and all of the old edited horror movies playing over and over on your TV make it one of the most entertaining and exciting times of year.

Back in 2006, we compiled a list of some of the best geek costumes on the market for those of you who do not yet have an idea as to what you want to be. It’s already been three years now, so we thought it was about time to compile another epic list of costume options for the undecided (which includes myself).

While checking these costumes out, keep some things in mind — most importantly: pretty much every costume that you see will have multiple styles of varying price and quality. The majority of the ones we have here are in the $30-$50 range, but you can find really high-quality “Deluxe” versions of the costume that will run you in the $100-$200 dollar range. These are for the folks who have money to spare and love authenticity. If you’re out of your freakin’ mind, there’s even Batman and Darth Vader costumes that will run you $700+ dollars. If you don’t like the one we’ve linked to, just search the character and check out all of the others that exist. Most costumes have children’s versions available, too. We’ve included some great kids’ costumes, but if you find an adult one you’d like for the little ones, just search it out! [...]

Once upon a time, someone somewhere created a sleeping bag re-creation of the Tauntaun corpse that Luke Skywalker used for warmth in that classic scene from Star Wars Episode V: The Empire Strikes Back. This someone was greatest online store ever created (proclaimed by I, anyway), ThinkGeek, and it was actually just a little April Fools silliness. Well, the gag was so popular, that people were called, papers were rustled, and ThinkGeek was given permission by George Lucas and Lucas Films to actually produce the sleeping bag, and you…yes, YOU can go and own one soon.

The sleeping bag (seen above, click to go large) is made of a nice, soft Tauntaun fur, and the inside is over-flowing with the natural comfort of intestinal embrace. Better yet (and my personal favorite touch) is the inclusion of a little lightsaber zipper, that allows you to cut open your desperate escape from the freezing cold winter every single time you use it!

If you got the reference in the title, you’re awesome and we’re putting you right up on the fridge.

Many of us cool kids are children of the ’80s, and as such, one of the greatest forms of entertainment ever to be created, is the Muppets. The Muppets are a creation of the late genius Jim Henson, who built an army of funny and lovable puppet characters who appeared in a countless amount of TV shows, specials, movies, music videos, cartoons, and everything in between. As life moved on and new generations of kids showed up, the Muppets faded off slowly, but never completely disappeared, making delightful cameo appearances on shows and events from time to time. But now, thanks to the massive Disney D23 Expo, we’ve learned that the Muppets are coming back in a big way, and their ready to take over the world again!

Back in March of 2008, we learned that we would finally be getting a brand new Muppet movie, with Forgetting Sarah Marshall team Jason Segel and Nick Stoller joining the Jim Henson Company to write and direct a new movie. [...]
