In Greek mythology, Odysseus outsmarted the Cyclops Polyphemus by using cunning and trickery. He told Polyphemus that his name was "Nobody." Later, when Odysseus and his men blinded the Cyclops, Polyphemus called for help, stating that "Nobody" was attacking him. This caused confusion among the other Cyclopes, allowing Odysseus and his men to escape. His clever use of deception showcases his heroic traits, as well as the theme of intelligence overcoming brute strength.
