Jack Black Talks Kung Fu And Tai Chi on 'The Late Late Show' (VIDEO)

Jack Black explained on 'The Late Late Show' (Weeknights, 12:35AM ET on CBS) that Kung Fu and Tai Chi are actually the same thing. But perhaps Craig Ferguson explained it best.

In talking about the groups of people who perform Tai Chi in the park, Ferguson said, "So you're telling me these people can kick my a** ... slowly?"

But one of the real strengths is how deceptively harmless a Kung Fu master can look. You have no idea what they're capable of until it's too late. Even knowing his skills, Ferguson still found himself sizing up Jet Li years ago.

"I wonder how many guys my size looked at him and thought, 'I could kick his a**,' just before they went to [the] hospital," he mused.
