It was a big week for the history books, and that was reflected in the most-watched and talked about viral videos of the past seven days.
We saw the return of Will Ferrell as George W. Bush, a few other Osama bin Laden-related videos, an emotional acceptance speech and an amazing ping pong shot. We even saw First Lady Michelle Obama do the Dougie.
