Anyone else remember those old "Choose your own adventure" books?

I picked up one at a yard sale today, and I thought I might google around...

I found some RPG type adventure choosing books, they're available online for free. He doesn't have a download link on his site, but if you just open the PDF, the go to File: Save...
You can still download it.

Then do as you please, print them out, rub them in your friends' faces, or just read it.
They aren't as childish as some may assume...
