1960: The High Crusade By Poul Anderson
October 14, 2008
A medieval village is transported to a technologically-advanced planet, where 12th century weaponry and terrestrial cunning miraculously defeat hoards of laser-toting aliens. This book proves that Earth is the USA of the galaxy – EARTH! EARTH! EARTH! – because we kick ass and take names. And that ain’t easy, because alien names are hard to spell, and our limited knowledge of xenobiology often makes finding their asses difficult. Recommended.
On a scale of medieval weapons ranging from the misericorde to the scramaseax, this book is: the zweihander.

Cheech and Chong's favourite book. Because, you see, they like marijuana.
