The excerpt that best supports the conclusion that Odysseus is clever is:
‘My name is Nohbdy: mother, father, and friends, everyone calls me Nohbdy.’
In this moment, Odysseus cleverly uses a false identity to deceive the Cyclops Polyphemus. By identifying himself as "Nohbdy," Odysseus ensures that when he blinds Polyphemus and the Cyclops calls for help, he will tell others that "Nohbdy" is attacking him, leading to further confusion and allowing Odysseus and his men to escape. This demonstrates Odysseus's quick thinking and resourcefulness.
