And when did the nose fall off too?

Nose does not carry any facial expression information, so there is no need for it.

I blame reddit for this one. :^) needs to be escaped for else the mouth floats away.

IMO monospace fonts can make the nose look ridiculous, but for other fonts I leave it in so the face is easier to read as a face.
