Yarn Bomb!

Yarn Bombing: the horticultural equivalent of dog sweaters.

So this, apparently, is 'Yarn Bombing' as recently witnessed on 3rd Street in Old City. It appeared mysteriously overnight, perpetrated by unknown citizen hipsters, as if by elf magic, and I suppose is conceived as high-minded, viral, civicdo-goodism but it just looks like B-grade foolishness to me.
