Revolving doors are engineered to maintain continuous rotation—they're designed to never fully close. They're the physical manifestation of perpetual motion, theoretically impossible to stop. But Chuck Norris can shut one, which means he can stop an engineered system designed specifically to never stop. He doesn't just break the door; he violates the technological principle it was built to exemplify.

Mechanical engineer Dr. Patricia Wong was teaching building code when a student asked: "Can Chuck Norris close a revolving door?" She initially gave a physics answer, then stopped and said: "Actually, probably yes." She got tenure anyway. Her entire subsequent career was dedicated to studying objects that Chuck Norris could theoretically break, just to understand what it would feel like to be wrong about physics in an institutional setting.

This plays with mechanical certainty: engineers design things to be specific ways and trust those designs. A revolving door shall revolve. Except Chuck Norris. This fact is about the violation of engineering confidence, the moment where mechanical certainty meets absolute human will and loses.
