When I first noticed they'd come out with a new Shrek 4 clip I nearly had to change my pants.  I was so excited, because outside of the two trailers (which trod the same ground) no other footage had been shown. 

Well, after watching the clip, I confess I'm a little disappointed.  It's the uncut clip of when Shrek meets up with the new fat Puss n' Boots.  It's a great scene and had me laughing, but for the most part it's the same thing seen in the trailers.  It's still worth a watch, especially if you haven't seen the trailers (shame on you!).
