Now if they could just figure out a way to let us all have a go forever, that'd be great.

We don't know what it is about James Corden that makes us wish they'd bring back stocks and rotten fruit throwing but he does. And while that might not be happening any time soon, at least we have a tennis pro with a 130 MPH serve firing tennis balls at him every now and then.

Tennis champ Novak Djokovic made an appearance on 'The Late Late Show' last night and was allowed to prove his mettle as Corden strapped on some protective gear, placed a water bottle on his helmet and challenged Djokovic and fellow guests Rainn Wilson and Jack Whitehall to serve until they knocked it off.
