Kiefer Sutherland attacks another poor, defenseless Christmas tree

Twitter/Kiefer Sutherland

Kiefer Sutherland is proving that he doesn't take himself too seriously: The Canadian actor's new holiday greeting card pokes fun at his somewhat infamous 2006 Christmas-tree incident.

Yesterday, the actor tweeted a "Happy holidays!" message to his Twitter followers, and attached the above photo of himself jokingly attacking a Christmas tree. For those worried the gorgeous ornaments would get destroyed, Sutherland helpfully included the caption "(just kidding)."

Good thing he made that clear, considering the actor has a bit of a history with Christmas trees.
