I like animated comedy, its comedy for 'our' generation. Sitcoms just don't do it anymore and implement way to many morals into the storyline.

Futurama differentiates itself enough from the other popular animated comedy series to be interesting. Animated comedy is, maybe silently, stigmatized for being to superficial. Indeed the stories don't go to deep most of the time and that is the appealing part of it, but now and then people have a need for extra emotions besides humor.

Bringing drama with a laugh, to me sounds impossible. obviously it can be done, but it almost always negates or even nullifies the drama part.

This episode was regular for almost the entire length, but it was build up to the end so ingeniously and unnoticeable that the end indeed made such an impact.

I think that if you compare this scene with the saddest scene from friends (in context) futurama wins by a land slide in sadness.
