A closer look

Seinfeld writer Dan O'Keefe based the hilariously cynical holiday of Festivus on a genuine, completely unironic tradition that his eccentric father invented in the nineteen sixties. The real-life family celebration did not feature an aluminum pole, but it did include the infamous Airing of Grievances, where his dad would passionately yell into a tape recorder about everything that had annoyed him over the past year. O'Keefe initially refused to write the concept into the show because he found his childhood memories deeply traumatizing, but the producers found it so wildly funny they forced him to include it. It is a beautiful testament to the power of television that one man's deeply uncomfortable familial psychological trauma was seamlessly transformed into a beloved international pop culture phenomenon that people still celebrate today
