Jimmy Fallon Can’t Beat Cameron Diaz in Kayak Racing

'Tonight Show' host Jimmy Fallon and superstar Cameron Diaz have a longstanding athletic rivalry that dominates both their actual friendship and just about any appearance Diaz might make on the late-night show. (Remember that terribly dangerous roller golf segment from earlier this year?) So, it should come as no surprise that they're at it again.

This time around, the duo are again on rollers (kayak-based ones, but still, so dangerous), careening around Fallon's studio and past some big obstacles (there's not just one, but two Elton John-centric gags here) on the path to indoor kayaking glory.

Fallon, however, has had enough. But even when the late-night host cheats, he still can't beat the athletic powerhouse that is Diaz. Just give up, dude.
