So on April Fools thinkgeek.com offered a number of fake items, including this awesome item: The TaunTaun sleeping bag!
Note that the inside pattern of the bag is entrails. My favorite part is that the zipper is shaped like a lightsaber.
What’s even better is that ThinkGeek claims that they got enough positive comments about it that they are going to see if they can get the rights to build and market it (see the original ad here).
While you’re there, you should check out the miniature trebuchet that they sell (throws small objects up to 20 feet)…
