This is an ongoing project so there are many in my personal library that need coverage. That said, _why’s guide is probably too well known for this list.
To me, something can be both quirky and well-known. Robin Williams and Mitch Hedberg's standup comedy both come to mind in this respect.
But if the idea is both quirky and rare/obscure, I can understand why¬_why.
_why's writing isn't uniquely quirky so much as it's an average day in Portland.
