While appearing on Radio Disney during a 'Take Over' session, Bieber got a cellphone call from Jaden Smith (Will Smith's son) and the voice of Oklahoma State football coach Mike Gundy shouted: "Come after me! I'm a man! I'm 40!" Most sports fans will recall those words from Gundy's epic tirade during the 2007 season in which he ripped an article in The Oklahoman that was critical of former starting quarterback Bobby Reid.
During the postgame rant following a win over Texas Tech, Gundy went off for a total of 3 minutes and 20 seconds about the article, including some classic lines that made it a viral sensation. It's racked up over 2,000,000 views to date and was featured in DJ Steve Porter's memorable mash-up "Press Hop." And now whenever Bieber takes a phone call, Gundy's words will live on for all the teenyboppers to hear.
Bieber explained to Radio Disney that he recently watched the video of Gundy's rant and thought it was funny, so he decided to make it his "ringtone for everything." As a bonus, Bieber also delivered his best Mike Gundy impression complete with accent.
