For those of you who may not be fanatics about Seinfeld as I am. Festivus is a "holiday" that was made up on the show by George Castanza's Dad. They weren't big on Christmas so his dad created Festivus to "celebrate" the holiday season in their own special way. If you want to read the full story about it, they even have a Wiki page, but here is an excerpt from the show:
George: Nothing. It’s a card from my dad.
Elaine: What is it? “Dear son, Happy Festivus”? What is Festivus?
George: It’s nothing.
Jerry: When George was growing up —
George: Jerry, NO!
Jerry: — his father hated all commercial and religious aspects of Christmas, so he made up his own holiday.
Elaine: Ohhhhh, and another piece of the puzzle falls into place.
Jerry: And instead of a tree, didn’t your father put up an aluminum pole?
George: Alright, Jerry, stop it!
Jerry: And weren’t there always Feats of Strength that always ended up with you crying?
George: I can’t take it any more, I’m going to work! You happy now?!
And so to honor my fellow Seinfeld friends, "I have a lot of problems with you people," and therefore will be making a donation to the Human Fund.
