^Just saw a great idea for a party on someone's profile: The
  "Ugly Sweater Party". Saw lots of pictures of people in ugly
  sweaters. Of course, with my luck, I'd be the guy who didn't
  know it was an ugly sweater party and ended up winning Ugliest
  Sweater prize. Good thing I don't own a sweater. Just saved
  myself the embarassment.^
