No one wears a pokerface better than Channing Tatum, who was positively smoldering during his game of Box of Lies on 'The Tonight Show Starring Jimmy Fallon.'

The purpose of the game is simple. Each contestant takes turns examining the contents of a box and describing it to his opponent. Of course, there's always the option to lie about what's inside -- but it's up to the competitor to decide if it's the truth.

While other celebrities have failed to restrain their laughter during Box of Lies (please refer to Kerry Washington's hilarious game), Channing clearly meant business. He did his best to keep a stoic expression on his face, although at times he totally cracked up.

If there's one thing better than watching Channing trying to maintain a pokerface, it's watching him goof around with Jimmy. The two pretended like they were fierce competitors, but clearly were having a blast.
