Thursday night was a double-whammy for 'Futurama' (Thu., 10PM ET on COM): it was the season finale and the series' 100th episode.

The episode revolved around the Planet Express team's 100th delivery and the subsequent celebration, during which Fry accidentally outs Leela as a mutant, fomenting a revolution and banishment.
