Katie Couric Pranks James Corden by Falling Down Stairs [Watch]
A lot of people did some pretty lame, not so funny April Fools jokes yesterday. Some people even got into some trouble.
Not Katie Couric. She is a sassy, classy lady and she knows how to do a prank right!
Can you spot the look of terror on James's face when he thinks Katie fell down the stairs...
