O. Henry Pun-Off Day is a lively celebration of pun lovers that takes place at the O. Henry Museum in Austin, Texas. This event gathers participants and spectators to enjoy clever wordplay through two main contests: one featuring prepared routines and another involving rapid-fire pun exchanges based on a given topic. Contestants share groan-worthy jokes and clever lines, while a judging panel scores their performances, with audience cheers helping to break ties. The event also includes music, food trucks, and a silent auction, creating a vibrant atmosphere. Attendees can celebrate by hosting mini pun-offs, sharing pun cards, or participating in pun-themed activities. The day honors William Sydney Porter, known as O. Henry, celebrated for his twist endings and clever language.
