The most epic pun battle ever fought between two men named Arin and Jon

Got an idea for a story, but not good enough to write it myself. <br><br>Arin and Jon are lifelong friends who have dedicated their lives to the world of puns. They've been training for years, and today is the day of the ultimate showdown. Armed with an arsenal of puns, they face off in a battle of wits (and groans) that will leave only one man standing.<br><br>Pick an environment and an audience and let the battle begin. <br><br>[Edit: the story doesn't have to be funny, but it would be nice if it tried to be funny! I would like it to have a more serious tone however, as it's a life or death battle]
