'Being Human' four-minute sneak peek ... and more Sam Witwer dancing

Want to see the first four minutes of tonight's Being Human? Of course you do, unless you're some sort of supernatural-hating communist. So check it out below. In tonight's episode, titled "Get Outta My Dreams, Get Into My Mouth," Liam is hunting vampires and Aidan starts to have vivid nightmares.

As if that's not juicy enough, before you watch tonight's ep, check out this blooper reel from last week that shows Sam Witwer's dance moves.
