Who doesn't love a highlight reel?

From the Olympics in London to singing along to the all-star concerts on the plaza, relive the funniest, silliest shenanigans from the show this year. Remember when Justin Bieber taught Matt how to tweet, or the time Scarlett Johansson did the weather forecast for Al?

See the anchors get silly in crazy costumes and show off their moves to the biggest songs of the year, from "Call Me Maybe" to "Gangnam Style."

Take a look at some of the reactions to our top picks and weigh in — what was your favorite moment?
