I got a #4 faded down to a #2 buzz about 2 weeks ago.  When I graduated highschool in '08, it was about a foot long.  I almost want to grow it long again but I have some cowlicks that make me look like an idiot unless my hair is over 8 inches long.  Its too ugly of a transition for me to handle, but I think ill grow it out after College so I can look stupid for a few months without the nice college girls being scared of me.  Fortunately, im in the Environmental Science program: one of the few majors that offer jobs where looking like a hippie is not only acceptable, but encouraged.
