As I just mentioned to someone a couple minutes ago... today I gave myself a reverse mullet. It's not that I meant to, exactly; I felt like chopping my hair shorter so it'd wash faster, I tied it back before cutting it, so it was fairly even when tied back. However, that means that when I let it down, it's much longer in front than in back -- the backmost hairs are maybe four inches long, while the frontmost make it from on top of my head to a bit below shoulderlength.
Heh heh heh. I am the anti-mullet.
