A hair book?  Why not?  Dumber ventures have succeeded.  I could not only write 200+ pages about my crown cover, but I could weave the covers for collector's editions and charge exorbinant amounts!  I can bag dandruff and sell it to be smoked or snorted (depending on your personal preference).  What's more, I could relocate to an area rampant with ticks, harvest a crop of them, and market the insects to allow readers of my book the first-hand experience of something that lived among my strands.  It's so ridiculous, it could work!

'Course, I'd have to find this more interesting than I do.  I enjoy digging the mine for another chunk of pyrite, but if you strung these segments together end to end and printed them out on looseleaf, I might have enough paper to create a baseball cap. 

Until I finish the book I'm not starting anytime soon, you'll have to take my word that I ardently rub my skull over my keyboard and monitor before submitting each entry.  Osmosis, my ****.  (Or, more accurately, my scalp.)
