In this episode, Jerry dates a woman who looks attractive sometimes and ugly at other times, Kramer returns to his old job at a bagel shop, and George gets out of buying Christmas gifts for his co-workers with fake donations to a made-up charity.
[3] At Tim Whatley's Hanukkah party, Elaine gives a man named Steve her default fake phone number when he hits on her.
After learning about Festivus from George and Jerry, Kramer becomes fascinated with the concept and meets with Frank Costanza, who invented the holiday to get out of the pandemonium of Christmas shopping.
To avoid buying gifts for his co-workers, George hands out cards for donations to "The Human Fund", a fake charity.
His boss, Mr. Kruger, decides to give a company donation to the Human Fund, and learns that the charity is bogus.
When Kramer first meets Gwen, he sees her unattractive side and does not recognize her when picketing outside the bagel store, claiming that she is more attractive than Jerry's actual girlfriend.
[4] The Human Fund was conceived by writer Jeff Schaffer and based on Christmas cards the Seinfeld staff would receive from Castle Rock.
[6] The Human Fund is the name of an actual organization based in Cleveland, Ohio established in 2005, eight years after the episode's airing.
[7] In the years since "The Strike" first aired, Festivus has entered popular culture and is celebrated annually, usually on December 23, as a tongue-in-cheek secular alternative to Hannukah and Christmas.
