Mathematics teacher and puzzle creator Tetsuya Miyamoto says he's probably watched Bruce Lee's "Enter the Dragon" at least 20 times.
Miyamoto, whose numerical and logical puzzle KenKen has achieved worldwide success over the past decade, was inspired as a teacher by the iconic scene in which Lee's character fools a bully who has picked a fight with him on a boat.
Antagonized with threats of violence and posed with the bully's question, "What's your style?" Lee responds, "My style? You can call it the art of fighting without fighting."
