Here's another classic from Klutze!
To bring thumb wrestling to the next level, Klutze invented the Sleeve of Doom, a sleek, shiny and sensational instrument of combat. Two contenders slide their hands in and clasp them together, poking their thumbs through the holes for an even playing field.
The book covers everything from classic challenges, strategies and training exercises to fake outs, battle cries and never-before-played games.
Who knew thumb wrestling could be so much fun?
