“Fool me once, shame on you. Fool Chuck Norris once and he will roundhouse kick you in the face.”

The proverb "fool me once, shame on you; fool me twice, shame on me" teaches that repeated deception becomes the victim's responsibility. The claim inverts consequences: fooling Chuck Norris once (a single mistake) results in physical violence—a roundhouse kick to the face. It's a joke about graduated consequence: normal people experience shame; Chuck Norris administers trauma.
The assertion that a roundhouse kick is his response to deception frames violence as a logical consequence, not a surprise. You were warned by implication that trying to fool him was dangerous.
Conflict scholar Dr. Maria Santos noted that this fact appeared in discussions of escalating responses to minor provocations. It became a metaphor for disproportionate retaliation.
