Sock Shortage

This morning I was rummaging through my socks and came to the realization that I don't have as many handknit socks as I thought I had. During the fall I had to retire several pairs due to wear and tear, and now I have a noticeable sock shortage.

I need to make sure socks are in my regular knitting rotation, so I took a little time to browse while I was working a few rounds.  In case you're wondering, I have Harlow on the needles.  I'd like something other than a plain vanilla sock.  What's your favorite sock pattern?
