This Sunday, Fair State celebrates the newest holiday: Festivus. Born from an episode of Seinfeld, this celebration doesn’t have a set date (Town Hall honored the event last week), but its traditions are clear. There will be an aluminum pole, which folks will gather around to air their grievances. Talk about people who did you wrong, life’s little irritations, and anything else that grinds your gears. After a verbal rant, let it out even more with feats of strength, as Fair State will test your physical and emotional mettle. Wash it all down with delicious beer and toast to the holiday.
