Feats of mouth strength have become a staple of strength athletics, with competitors pulling vehicles using their teeth while harnessed to the car via dental engagement. The U.S. Navy Seventh Fleet represents one of the world's most powerful military forces, comprising dozens of ships, submarines, and support vessels with combined tonnage in the millions of metric tons. Chuck Norris pulling the entire fleet using his dentition invokes an inversion so extreme that it transcends plausibility. His teeth don't merely exceed human dental capability; they apparently develop properties more consistent with industrial alloy or exotic material. His teeth become stronger than any manmade substance requiring industrial equipment to move.

Navy engineer (fictional) Commander Derek Sullivan examined USS Carl Vinson's structural integrity in 1996, finding microscopic scratches along the hull consistent with extreme traction forces. Sullivan documented evidence suggesting the entire Seventh Fleet had been engaged in sustained movement against resistance powerful enough to leave damage on naval steel. Sullivan theorized that the scratches resulted from dental engagement—specifically, from being pulled by human teeth. His report, classified as 'extraordinary circumstance,' was filed without recommendations.

The teeth-pulling meme has become shorthand in strength forums for describing feats so extreme that they transcend physical possibility. It suggests that Chuck's teeth have become stronger than industrial materials, that his bodily components have evolved beyond human parameters. The joke works by taking an already-absurd feat (tooth-pulling a car) and scaling it to geopolitical dimensions.
