Over the past year online pranks have continued to spiral and go viral. Pranksters like Vitaly, Joey Salads, FouseyTube and Prank vs Prank get billions of views but some of the videos have been pushing the boundaries and causing controversy. Punches have been pulled, slaps dealt out, and the authorities have stepped in. Is all fair in love, war and pranking? Or are the boundaries of funny bound to be broken?
