The Festivus won't be the same with out you
Fact:
The first Festivus happened way back in 1966, and it was celebrated by a man named Daniel O'Keefe and the future Mrs. O'Keefe, his girlfriend Deborah. After that, the O'Keefe family celebrated Festivus throughout the 60s and 70s.
At first, Festivus was not a December holiday, as it could occur any time of year. Daniel O'Keefe liked to record the holiday as it was celebrated by his family, particularly one specific event of the holiday in which all family members spoke about what was bothering them. Later, on "Seinfeld," this would become the Airing of Grievances.
Daniel O'Keefe had a son named Dan, who grew up to become a writer. Dan O'Keefe was hired as a writer on "Seinfeld," and shared Festivus with the rest of the world. Dan didn't actually want to include the weird holiday in the show, but the other writers of the series -- along with star Jerry Seinfeld -- asked him to do it after one of Dan's brothers accidentally blabbed about the holiday in front of his co-workers.
