It also has a scene where the mayor gets the envelope for who won the Christmas light decoration contest and he lies about who's name was in it and gives the award to the neighbor lady (the same one who has affection for the Grinch) because he's trying to woo her.
There's a bunch of stuff like that in the extended cut.
