If you're anything like us, you probably have difficulty remembering which Jonas brother is which. That's why we were glad when Joe Jonas grew his hair out a little bit between 2008 and 2009; it made him easier to identify.
A few years later, he cut his hair short, and our confusion returned. Now the band is back together, though, we might see him distinguish himself with a longer mane of hair yet again. It feels like the right thing to do for nostalgia purposes.
