Cook, Menounos say 'Go Celtics!!!!!'

On Tuesday, Maria Menounos and Michael Chiklis showed their passion for the Boston Celtics.

Now, thanks to the Celtics' official YouTube channel, they're back to fire up the men in green for Game 6 against the Miami Heat (side note: there's a reason we used five exclamation points in this headline).

Oh, and Dane Cook came along as well.
