"As everybody knows, a poke will contain and conceal a marketable pig;-- even two actively wallowing pigs, according to Chaucer..."
If you're having a slow night, go down to your local university library and pick up a copy of Shakespeare's Motley, by Leslie Hotson (published by Rupert Hart-Davis, London, 1952). It's an odd little book about the costume of Shakespeare's fools, which is not exactly what you've always thought it was. Unless you're Leslie Hotson's child, in which case it probably is exactly what you've always thought it was.
If anybody needs me, I'll be wallowing in my poke. Rather, I'll be reading this book while wrapped up in a blanket. Have a great night.
