There are few mysteries in life that are as perplexing as the mystery of the missing sock. No matter how hard you try to keep pairs of socks together, invariably one of them ventures out into the netherworld never to be found again.

Lost Sock Memorial Day is a day to honor all those disappeared socks.

How to Celebrate

  • Throw out all the single leftover socks.
  • Use the leftover socks as cleaning cloths. Or spend the day making sock monkeys out of the socks that have sadly lost their partners to the sock blackhole.
  • Have a minute of silence for all the socks you have lost.

Did You Know…

...that the feet have about 250,000 sweat glands that are capable of producing about 1 cup of sweat a day?
