Well, it looks like the evil pink and cream argyle sock has cleared off on its own. Most likely, it escaped out the hole in the washing machine, but I can't prove it.
I suspect it is lying in wait somewhere, looking innocent (a la video tape a la "Ring") while waiting for someone to pick it up.
I say, "Good luck, evil sock. People generally don't take home strange socks off the street no matter how cute the are--even if they are a cashmere blend!"
