I know everyone knows about the website but I recently bought the book for ten dollars at Borders and it is fucking hilarious. The ultimate Guide to ninjas.
I have a shirt from that page :-)
It really is a great website. And the book is awesome. I have never read something that has made me lol before.
It's been on my amazon wishlist since before it was even done. I'm hoping I'll get it for Christmas.
There is no way I can give young Robert Hamburger enough praise.
