Halle Berry and Jimmy Fallon rolled down a mat and it was pretty cute

Celebrities doing things kids do: who knew that could be so entertaining? On Tuesday night, Jimmy Fallon invited Halle Berry to somersault with him in a segment that bordered on "Tonight Show" self-parody. The most painful part of the segment is when it ends, and you, the captivated viewer, realize you just spent a minute watching two people tumble down a gym mat -- and you liked it.
