Rob Lowe won a comedy face-off with Ricky Gervais - and the British star got his revenge by shooting the actor in the eye with a dart.
The pair were joking around between takes on their forthcoming movie This Side of the Truth when the Brothers and Sisters star beat Gervais in a war of words.
But The Office creator wasn't going down without a fight - and shot Lowe in the face with a dart gun to get even with him.
Lowe says, "I had such fun giving him hell. It was merciless. He had these amazing dart guns. We were running around just for fun and that was the only way he could get me back. He had to resort to physical violence because he couldn't take me on verbally. Only physically."
