You can't tell a book by its cover.

Ryan Phillippe apparently has studied Tae Kwon Do since he was 8 years old; he's competed in tournaments and has even taught kids.

On Wednesday's (weekdays, syndicated), Phillippe gave some examples of his martial arts skills. First, he said, "I'm going to do an elbow strike, in a suit jacket," though, at DeGeneres's urging, and to the delight of the squealing audience, he took his coat off. He then promptly split a wood board in half with his elbow, and demonstrated a high kick for DeGeneres.

Though DeGeneres' bad back prevented her from getting a lesson, she still had a surprise present for the star.
