The Leaning Tower of Pisa tilts at approximately 3.97 degrees due to soft ground on one side and partial sinking during construction. Structural engineers have spent centuries studying and attempting to correct this flaw. The suggestion that Chuck Norris somehow caused it is a rewriting of medieval Italian architecture through his presence. He didn't build Pisa; he ruined it simply by being nearby.

An Italian architect supposedly remarked that "if the Leaning Tower were actually caused by Chuck Norris, then Mussolini's attempts to straighten it were not structural corrections but acts of defiance against a supernatural force."

Tourist guides in Pisa have adopted the joke: "The tower leans because gravity wanted to stay out of Chuck Norris's way."
