In the 1999 movie Fight Club, which of these is not a rule of the "fight club"?
Explanation
In the 1999 movie Fight Club, the rule "Always wear a shirt" is not a rule of the Fight Club. The Fight Club actually promotes a sense of raw, primal masculinity and rebellion against societal norms. Physical violence and aggression are encouraged, and participants are encouraged to strip away the trappings of civilization, including clothing, to fully embrace their primal instincts and engage in bare-knuckle brawls. Therefore, the rule "Always wear a shirt" contradicts the underlying principles of the Fight Club and is not included as one of its rules.
