Nice promo, but thas was the most ridiculous screen-ripping-paws-effect I have ever seen. Unless it was for a Muppets halloween episode, but I am pretty sure it wasn't :)
My guess is that it transitioned into a Grimm promo, which features a "big bad wolf" in the pilot.I have to say that even though fans were disappointed by Chuck premiering later, it has done wonders for Chuck's promotion levels.Last year, they premiered in the same week as all the new shows and it got very little promotion because NBC's priority was the new shows.
No flaming, baiting, trolling, expletives, or racism allowed. And NO DISCUSSIONS of the actor's personal lives ever.
