GATHER around the Festivus pole and listen to a tale about a real holiday made fictional and then real again, a tale that touches on philosophy, King Lear, the pool at the Chateau Marmont hotel, a paper bag with a clock inside and, oh yes, a television show about nothing.

The first surprise is that from Tampa Bay, Fla., to Washington, from Austin, Tex., to Oxford, Ohio, many real people are holding parties celebrating Festivus, a holiday most believe was invented on an episode of "Seinfeld" first broadcast the week before Christmas in 1997.

"More and more people are familiar with what Festivus is, and it's growing," said Jennifer Galdes, a Chicago restaurant publicist who organized her first Festivus party three years ago. "This year many more people, when they got the invite, responded with, 'Will there be an airing of the grievances and feats of strength?' "

Those two rituals -- accusing others of being a disappointment and wrestling -- are traditions of Festivus as explained on the show by the character Frank Costanza. On that episode he tells Kramer that he invented the holiday when his children were young and he found himself in a department store tug of war with another Christmas shopper over a doll. "I realized there had to be a better way," Frank says.
