I've never thought Justin Bieber was all that cool, until this morning.

On an interview with Radio Disney, Justin Bieber's phone rang and his ringtone was Mike Gundy's famous "I'm a man" rant.  Justin explains how the rant came to be his ringtone.

In a pretty sweet turn of events, Gundy's phone rang during a presser, and you'll never believe what his ringtone is.
