I thought this was a really funny episode of Futurama. I enjoyed the story a lot.
I am not able to describe this episode, so I am going to use TV.com's summary of the episode instead of coming up with my own:
The Professor decides to ship hazardous cargo to the outer reaches of space, but the course chartered takes the ship through some environmentally sensitive areas-including the penguin refuge on Pluto. Leela refuses to transport the dangerous cargo, so the Professor removes her from command and installs Bender as captain. While Bender is piloting the ship, he allows his attention to drift and accidentally showers the penguins with oily goop. As punishment for his crime, Bender gets 5 hours of community service helping clean up the mess.
