OK, I don't get it. The plot of Fanboys is a group of kids breaking into the Skywalker Ranch to give their friend a screening of The Phantom Menace before he dies of cancer, so I get the Darth Vader part. Referencing Darth Vader makes sense. But why the 40-Year-Old Virgin parody? For a movie that so embraces geekiness, it seems out-of-character to be pointing out the perpetual virginity of fanboys. Also, it's redundant. Of course a guy in a Darth Vader mask isn't having sex. We all know the Boba Fetts are getting all the real P action.
