The Absence of Barneys Laugh...

Not sure if anyone else caught this, but did anyone else notice that Barney did not Laugh once in the whole movie?! One of the Charms about the old TV Show was Barneys laugh, but in this Movie, He didnt do it once!!! He did a couple times when he was dressed as the Lady at the Poker game, but that wasnt Barneys laugh. I wander if Mel Blanc had a problem doing the laugh in his later years..
