We're calling it early, this is how you do your April Fools' Day prank.

Sydney radio station Nova 96.9's Fitzy and Wippa (the two Aussiest names there ever were for radio DJs) decided to pull an early prank on their own bosses and pre-recorded a segment in which Fitzy quits live on air in quite expletive fashion. How did they fool the producers into thinking it was going out to the nation live? By getting the station engineers to pipe it into the office speaker system.

Watch as they attempt to mime along to their panto argument, and their bosses sprint from their offices to the studio faster than they've probably ever run in their lives. Brilliant.
