8A. Invasion of the Idiot Dog Brain

Zim's house has a few security glitches, so Zim replaces the artificial intelligence brain. GIR's job is to watch the data beam for any fluctuations. After Zim installs the new brain, the beam hits GIR when he tries to get his toy moose and he ends up in the computer. GIR really annoys Zim for one whole year, then rampages through the city...for tacos. So GIR finally gets his tacos and Zim returns the computer back to normal. Things are more normal now than they ever were.

8B. Bad, Bad Rubber Piggy

After watching Professor Membrane's show about using a space-time object replacement device, Zim decides to create one of his own. When he tries to send his hunter-destroyer machine into the past, the machine doesn't accept the hunter-destroyer, so Zim angrily chucks GIR's rubber piggy into the time machine only to see that it works. So Zim impends temporal doom upon Dib through piggies. Zim kills Dib, but Professor Membrane puts him in a machine called the Megaboy 3000, so Dib goes back to destroy Zim. Dib gets ready to throw a final punch on Zim when Zim throws one more piggy telling himself in the past to never use the time machine. Dib is back to his normal self, but Zim's brain was replaced by that last piggy.
