Katie Couric Pranks James Corden [VIDEO]

This has to be one of the BEST April Fool's Jokes that was shown on TV yesterday. Katie Couric was a guest on The Late Late Show with James Corden, and she and the staff conspired to prank the host, James Corden. As Corden introduced Couric, it looked like she took a really nasty fall down the stairs! Corden rushed over to her aid, swearing on the way, as it looked like she was really injured! April Fools!
