Fall season 2012: Quick looks at 'Hawaii Five-0'

It's here, it's here, it's heeeeerrrre!!!! The 2012 fall season begins in just a few hours, which means ... new episodes of "How I Met Your Mother" and "Hawaii Five-0," to mention just a couple of major new entries tonight. ("Castle" arrives, too.) 

 First, a couple of clips from "H-5-0" fresh off the clip factory line. McGarrett's mom is in this one - yes, that's Christine Lahti - and Wo Fat, the evil Wo Fat, I might add, is in chains. But for how long? There's a scene tonight that may remind you of one from "The Dark Knight Rises" and from the premiere of this series, entering its third season. It's quite good and you are left to ponder: How do they get those toys (and why don't the cops ever have them?)
