so, Microsoft came out with an emotion detector. Went through
  some pictures. Some neutral faces, some happy faces, all with
  bits of other emotions mixed in. But this one? A statistically
  perfect happiness level of 1. Look at the lowness of the other
  numbers? They don't get much lower than that == I hardly
  recognize myself in that picture. Short hair, no beard,
  different glasses. But yup - that's me. Looks like someone else
  to me but that's me :P [1]kenneth-udut-happiness-one
