If you weren’t able to make it to Comic-Con and get Michael Nelson to firmly press his preferred writing utensil onto a solid, dry surface of your choosing, and you happen to have a couple hundred dollars to spare, now’s your chance for vindication. Legend Films has put up a set of three Rifftrax posters on eBay, each autographed by that episode’s riffers. The movies are 300, Star Trek VI, and The Phantom Menace. (That brings the count to three Mike and Kevin signatures, and two Bill signatures.) The bidding is at $91, as I type this. Good luck, you wasteful spenders.
