Odysseus and his men broke into the Cyclopes home to steal food and goods. The cyclopes did wake up and started to attack and eat Odysseus' men. Odysseus did blind the cyclopes, and tricked him by saying his name is nobody to prevent cyclopes from being able to successfully call for help when Odysseus enacts his escape plan. Odysseus couldn't help but get his credit for doing what he did. He says who he was to the cyclopes. This put him and his men in big danger. This small mistake made Odysseus' trip back home 10 years longer and all his men die.
