A Boy and His Hair

My oldest son has long hair (see proof here ) and is ready for a change. Not short, but a new style. He's very excited (as excited as an eleven year old boy can be about hair) about this:

Joe Jonas (center) has the look my boy wants to imitate. I'm on the fence about it and trying not to fall off. Is it just me, or is it a piece-y mullet? A party in the front and simultaneous party in the back kinda mullet? I'm all for risky hair, especially when you're a kid. Since once one becomes an adult it is often difficult to pull it off if you've got a job that says; conservative, please. But a mullet? I have this fear that he'll hate it once the deed is done. And I'll try to keep the rain of hair from sticking to his tears as I shave it all off onto the kitchen floor.
