Unfortuantly, I don't think the boys were referencing Tom Waits with "Downtown Train". Rod Stewart made a cover of the the song and the video looked a lot like the scen in Daredevil. I would like to hope that they listen to Tom Waits since he is pretty darn cool (or that the video i saw was his version of the song and not Rod Stewarts).
But i learned a ver important thing from this rifftrax. Colin Ferrel is sober is an illogical statement.
I loathe him so much, i think that is why i listen to this riff the most (this one an eragon)
