This episode follows a common track of the Simpsons writers - misdirection. Often in every joke of theirs, they seem to go a normal route when they veer off into a crazy one. Easily enjoyable as a laugh a minute ride, it soon turns into a roller-coaster of emotions. Fulfilling both to the heart and the soul.
The Episode begins with Fry discovering that his old Pizza place has been unearthed, and with it his old dog, fossilized. His only friend back in the day, Fry gets Dr. Fransworth to agree to clone him. But Fry's overindulgence in his old best friend leaves his new best friend feeling neglected. Bender's efforts to get Fry's attention are very laughable and who can resist a dog singing 'walking on sunshine'. But the denouement comes as a wow. And a fine ending recalling such classics as Dr. Strangelove, this is a standalone episode yet it works so much as an integral part of the Futurama universe. This episode just reaffirms why the series is so beloved. In all its edginess and the abounding humor, the show still has heart. What more can you ask for?
