Worlds War I

Worlds War I started because Professor Hubert J. Farnsworth's time machine sent all the Earthicans back to the time of the dinosaurs, which caused their evolution to speed up. The Omicron Persei Empire believed them to be a threat and attacked Earth. Several other planets joined forces with Earth. The war was ended by Philip J. Fry when he was sent to a P.O.W. Camp and the Omicronians found out that the Earthicans were stupid and called back all their forces. This made Fry win the 1917 Savey Awards.
