ZIM has been banished from the Irken Empire after foiling Operation Impending Doom I, which was set in place in order to take control of the most of the universe. Operation Impending Doom II is now in place, with new Invaders set on planets to destroy any resistance, and ZIM comes crawling back, begging for a second chance. The Almighty Tallest sends him to a tiny galaxy on the edge of the universe, hoping he'll die on the way. They give him a malfunctioning SIR unit made from scrap metal, which has dubbed itself GIR. What ZIM finds is Earth, and he sets up a house with all his alien stuff underground beneath it.

ZIM decides that the Roboparents aren't ready for human interaction yet, and takes them down to the lab. He straps them to chairs, and inserts a disc into the computer on good parenting. GIR gets bored and starts changing the channels on the monitors around the room to things like a kung fu movie, "Poke of Doom". Finally, they are done and head off to Parent Teacher Night. Dib and Gaz are there with Prof. Membrane transmitting from his lab with his floating screen. Dib is curious about ZIM's parents and watches them closely for any mistakes. Everything is fine in the beginning, until Robomom goes on a poking rampage, and Robodad starts running into walls. ZIM begs to go home, but Roboparents say that they want to stay a little longer. Finally, ZIM fakes a broken back and the Roboparents decide that it's about time they head home.

23. Mysterious Mysteries
Guest Stars: Rodger Bumpass (Professor Membrane) John Garry (Mysterious Mysteries Anchor)

Mysterious Mysteries's ratings are dropping because they are running out of stories. After another employee at Mysterious Mysteries suggests using something from the Dib Archives, the anchor decides that he must take drastic measures in order to keep his job. Inside is a movie disc, which the anchor watches, and a decides to air it as it is most likely better than the other story option. Dib has finally made it onto his favorite show, Mysterious Mysteries. The show runs the tape-- a very short clip of ZIM and GIR, out of disguise in a forest. But the tape doesn't prove much, and ZIM comes on the show, in disquise, to deny the accusations. In a "dramatic" re-enactment, featuring terrible actors and costumes, ZIM accusses Dib of being a bully and faking the video. ZIM also goes on to prove that Dib is crazy, and his classmates agree. The Mysterious Mysteries anchor interviews Gaz next, and she gives a re-enactment of how Dib and ZIM are both amazingly stupid, and dragged her into the whole thing. A "surprise guest" comes on next, a blurred-out face, which has a hard time following it's subject, who identifies itself as Stacy, "a chubby lady hiding in the bushes", and saw the whole thing--but we can easily see it's just GIR. His re-enactment tells of a giant crime-fighting space squirrel who was there at the scene.

The anchor's final word: Dib is crazy. GIR: definitely crazy. He feels bad for ZIM, but he's probably crazy, too. But not an alien.

Later, Dib finds a kid that looks just like him in his room. The kid claims to be Dib from the future. In the future, ZIM had sabotaged PEG, and it opened up a quick time rip that sent Dib back in time. He tells Dib about ZIM's plan, and Dib goes off to stop ZIM. When Dib reaches the warehouse where ZIM is keeping his sabotage drill, four gnomes appear around him and transform into giant insects that capture him. Turns out that Future Dib is actually DIB2, a robot sent by ZIM to trick Dib. ZIM throws him into a cage, and when Dib uses his computer to take control of DIB2's speech, a rabid monkey is released into the cage to stop him. Dib succeeds in gaining control, but promptly gets attacked by the monkey. Gaz can hear all this, and gets angry at DIB2, thinking that Dib's just acting weird, and starts beating him up, and soon notices that he's a robot. Membrane, meanwhile, is waiting for Dib and Gaz to show up so that he can introduce them to the audience that is impatiently waiting for PEG to be activated. The audience grows reckless, and one kid throws his ice cream at Membrane. Membrane is angry and seals PEG up forever, saying that they don't deserve it. In the end, the world still needs fuel for energy, Membrane is still a neglective parent, DIB2 is Gaz's robot slave, ZIM's irritated that his plan failed, but is happy that Dib never managed to get out of the cage, and is trapped with the rabid monkey for the rest of his life.
