Channing Tatum continued his charm offensive on Friday night on The Tonight Show, where Jimmy Fallon challenged him to an arm-wrestling match. While Fallon would normally be no match for the brawny Tatum, this was mostly a war of words, with each man declaring what he would do after he won. (Tatum: "After I win, I'm gonna buy a boat, and I'm gonna name it S.S.H.H.H. So whenever somebody asks me how I pronounce it, I can be like, 'Shhhhhh!'") The crowd was vocally pro-Channing (whatever happened to rooting for the underdog?), but it was probably because they could see his biceps rippling through his suit.
