Rifftrax is an audio commentary service brought to you by Mike Nelson, the second host and head writer of Mystery Science Theater 3000. Mike Nelson and his fellow "riffers" poke fun at your favorite -- and not so favorite -- movies, as you watch along with them. Their award winning humor, satire, and antics are available for download as MP3 files for a small fee at Rifftrax.com. All you have to do is provide the movie, load the corresponding Rifftrax file on your MP3 Player, and sync 'em. Then you're ready to enjoy movies (and a few TV shows) like you never have before... that is, unless you've seen MST3k, of course. Learn everything you need to know in this video review and tour, which includes a few quick clips of the guys "riffing" Transformers and Spider-Man.
