I introduced my parents to this little ditty last year. We watched it at least a dozen times. Laughed hilariously. Imitated. Parroted and charaded as this singer. Everything was fine until our church sang O Holy Night last Christmas eve. We dissolved in a puddle of hysterics and shaking and were absolutely rendered useless singers.
Watch this link at your own risk. If you have any plans to sing O Holy Night over the next month… you might want to abstain so as not to have the same fate as mine!
