Tilda Swinton, one of the strangest people in the history of the world, did the above. It will happen again. There is a reason she spawned this comedy Twitter account:
I sit in a puddle, and pluck every spine from a hedgehog.He waddles away unencumbered.The year is 1783.I have created the guinea pig.
