Mixing athletes and television analysts isn't always a great idea. Just ask Tim McCarver and Deion Sanders. But occasionally breaking down the wall between words and actions can be downright entertaining.

Monday night, after dispatching Radek Stepanek with ease at the U.S. Open, Novak Djokovic challenged John McEnroe, calling the match from the booth, to come down and take some non-verbal shots on the court. Never one to shrink from a challenge, McEnroe jogged out and as the video above shows, held his own in the light-hearted rally.

Light-hearted might not be quite the phrase anyone would use to describe Skip Bayless, but he took his place opposite an athlete Tuesday morning, when Chad Ochocinco appeared on First Take. From Ochocinco disagreeing with Bayless that he's a better receiver than Terrell Owens to defending his kicking skills, it was, well, interesting.

• Before the showdown, 64 percent of SN thought Ochocinco would best Bayless.
• And by the time it ended, 66 percent felt Ochocinco came out with the win.
