Missing scene?

I have a feeling that I know one of the scenes that will show up on the inevitable unrated version release. On the third Christmas, when they were at Vince Vaughns characters mothers house, his mother tells Connor (the older boy of Vaughns brother) not to eat a brownie he was holding, saying "Those are grandmas 'special brownies.'" I found it odd that they left this in the movie, because there is never any reference to it again. I expected to see a later scene with the boy acting high. Such a scene certainly wouldn't be allowed in a PG-13 rated movie censored by the MPAA pinheads. (The movie "It's Complicated" was rated R recently because in one scene a couple characters smoke pot and, horror of horrors, nothing terrible happens because of it. Telling the truth offends the MPAA so badly they'll do anything to keep the kids ignorant.) I expect that there will be a scene with the Connor character rolling laughing or doing something silly in the unrated version.
