In his years as a rock n' roll manager, Peter Mensch has certainly seen more than his share of childish behavior. Now, Mensch, who manages such big names as Metallica and Red Hot Chili Peppers, wants to bring his expertise to help put formerly squeaky-clean pop star Justin Bieber in his proper place.

“I’d take Bieber to the woodshed and spank him,” he tells the infamous U.K. tabloid the Sun.

The quote comes following a spell of events which saw the 19-year old with a lot of money acting like, well, a 19-year old with a lot of money. This past month alone has seen the Canadian make headlines for, to name a few things, allegedly spitting on a neighbor, allegedly cursing out reporters and allegedly allowing his house to be used as a giant bong. Mensch, which means "man" in Yiddish, says the problem would disappear with the right amount of discipline, which he believes no one in Bieber's camp is, um, man enough to administer.

“His manager Scooter Braun is scared s---less," he continues.

Still, Mensch, like so many of us, is looking forward to a day when every action by Bieber, who is on record as being a Metallica fan, isn't splayed across every tabloid and website. "I don’t know what Bieber’s problem is," he adds. "His career is over in three years anyway.”

That's a scary thought. Imagine what kinds of trouble Bieber will be getting into when he has even more time on his hands.
