Freedom Day

Freedom Day is when all Earthicans celebrate their freedom. Evidently, it has evolved from the 4th of July in the 21st century. The traditional Freedom Day chant is "Freedom, freedom, freedom, oy! Freedom, freedom, freedom, oy!" while performing a sort of Hopak dance. In 3002, new meaning was given to Freedom Day when Earth was enslaved by the Decapodians. Dr. John Zoidberg saved the planet, ensuring the planet's continued freedom.

Given Fry was not informed of the holiday before 3002, it is suggestible that the holiday is not annual.
