You may be aware of the Underpant Gnomes. I'm affected by their close cousins, the Sock Gnomes. Different name, but their business plan seems to be very similar:
Unfortunately, the Sock Gnomes seem to steal one sock of a pair only. Which leaves me with a huge amount of single socks and drives me crazy each morning.
But today I launched my counter attack:
40 pairs of the same socks. Hopefully this will teach those little buggers a lesson.
