We’re not quite sure why Quinton ‘Rampage’ Jackson decided to prank call former UFC middleweight Chael Sonnen, but we’re very glad he does.

During a recent Twitch.tv video game broadcast Rampage Jackson prank called ‘The American Gangster’ Chael Sonnen and pretended that he found Sonnen’s number on his girlfriend’s phone. Sonnen said he caught on pretty quick and was trying to play along.

After the gig was up, Rampage and Sonnen discusses life and their careers in what turned out to be a pretty cool phone call.
