Happy Festivus! Let the airing of the grievances begin!
If you are a fan of Seinfeld like I am, then you know all about the nondenominational holiday Festivus. Celebrated on December 23, the day before Christmas Eve, the holiday involves a metal pole (instead of a Christmas tree). Instead of exchanging gifts, participants are encouraged to air their grievances. After that comes the feats of strength (pushups, for example). The party continues until the head of the family is wrestled to the floor.
The Seinfeld cast explains Festivus above.
