This episode is a very well plotted one and can do the one thing most sitcoms cannot, being a hilarious show with some emotional scenes that can still make you laugh yet feel for the characters at the same time.
Bender never being able to achieve his lifelong dream of being a Globetrotter makes you laugh at his idea of a dream but also has some scenes that make you realise he'll never be completely happy.
Fry and Leela somehow getting married, Fry thinking he must have done some great gesture and Leela completely convinced that Fry tricked her by drugging or hypnotising her makes you laugh yet feel for Fry, especially at the end where the one thing that made Leela love him was destroyed and all hope was gone.
Farnsworth was hilarious in this episode with one of those frequent "Good news everyone" before sending the crew to gather cronatons, which destroyed an entire civilisation, the doomsday devices and the super-atomic super men.
The time skips are hilarious, especially Amy's, Zoidberg's and Farnsworth's aswell as the kids down at the soial security office, though why nobody else aged, I'll never understand. The news report skipping was hilarious aswell and this episode proves that Futurama should never have been cancelled.
