Irony in Overachievers' Competition

Read the following excerpt from a satirical story:

"In the quaint village of Overachievers, the townsfolk held an annual competition for the 'Most Futile Achievement.' Contestants vied for the prestigious Golden Trophy of Pointlessness. This year, a grandmother claimed victory with her homemade air purifier that did nothing more than circulate stale air. The villagers applauded her innovation, as she proudly marched across the stage, while the runner-up, a teenager, presented his invention of a device that could toast bread but only when you weren't hungry. As the crowd cheered, they remarked, 'What a genius! Finally, a smart way to waste our time!'
