"The Man Who Came to Be Dinner" is the tenth episode of Season 26. It is the only episode outside of the Treehouse of Horror series to focus on Kang and Kodos.
The Simpsons go to Diz-Nee-Land where the lines for the rides are terrible, except for this one rocket called "Rocket to Your Doom" that takes them to the home planet of Kang and Kodos, Rigel VII where the inhabitants try to eat Homer in a giant fondue.
The Simpsons go to Diz-Nee-Land. After a really long journey, they hate all of the lame games and rides they visit, and choose to go to "Journey to your Doom", a just-opened ride which isn't on the map.
They get in, and it immediately transforms into a space ship. At first, the family is skeptical, but a screen appears, and Kang and Kodos tell them that they are being taken to Rigel 7.
At the planet, Kang and Kodos show them around on a giant pet cage, and the Simpsons are informed they are prisoners. Then they are taken as exhibitions to a Zoo, and after a while, they are informed they must choose one of them to be dined in a ritual. Everybody votes for Homer; even he changes his vote from Bart to himself after seeing the other votes.
After, we can see Homer walking in something that looks like a bacon underwear, to be eaten; but he gets rescued by some hippie-looking Rigelians who believe that eating other sentient species is wrong. After an excessive party, he gets on another space ship, only for one, that also pleases all desires, but he realizes he wont enjoy it without his family and goes back to rescue them.
The Rigelians, in the mean time, have chosen to eat the rest of the family, and they are glazed over giant plates with some lettuce and tomato. When Homer offers to be eaten instead, he gets put on a similar plate, and bothers the cook by eating the glaze and claiming he didn't get any.
The Rigelian queen then eats Homer's previously off-camera severed buttock and gets poisoned because of the fast food life they all eat; even Lisa is the worst polluted of them all. The queen dies, and the Simpsons get sent home, on a space ship that looks like the interior of the original starship Enterprise. They set course to Earth, but after a call from Abe, the family plans to go anywhere else but home. Then, the credits happen over a montage of several images spoofing Star Trek TV and movie scenes.
The episode was originally scheduled to air on May 19, 2013 as the finale of Season 24, but was replaced by "Dangers on a Train". As a result, the production code is much older than the rest of Season 26.
The episode received negative reviews from critics. Dennis Perkins of The A.V. Club was highly critical of the episode, giving it a D+ and saying, "It would be a lot easier to make the case that The Simpsons still has value if the people behind the show seemed to give a damn.
But an episode like 'The Man Who Came to Be Dinner' is a product of such slapdash, breezy disregard for what makes The SimpsonsThe Simpsons that it functions as a dispiriting signpost to the show's hastening irrelevance." He criticized how the episode repeated the scene in which Homer eats potato chips in zero gravity from the season 5 episode "Deep Space Homer".
Perkins likened the episode's ending in which everything returns to normal to the controversially hated season 9 episode "The Principal and the Pauper", and said "The Simpsons have met The Great Gazoo".
