The Geeky Computer Guys (also called the Star Trek Nerds) are two male college students who sometimes help out the boys in times of trouble. They have shown to be useful and talented in both science as well as special effects, but also to get into squabbles with each other over trivial things, such as the number of episodes in Star Trek: The Original Series.
They made their first appearance in "Fourth Grade", where they build two time machines for the boys, in order to return to the third grade.
They reappeared briefly in "Freak Strike", where they helped the boys attach a set of prosthetic testes to Butters' chin so he can go on the Maury Povich show, in exchange for an edited copy of Star Wars Episode I: the Phantom Menace.
Both of the nerds wear sandals and round-framed glasses. The first nerd wears light blue shorts, a navy blue shirt with the words "Resistance is futile!" written in green, and a green coat. He has long blond hair in the style of a ponytail.
The other nerd wears green pants, a black shirt with the words "Yeah, resistance is futile!" written in red, and a black wrist brace. He has short brown hair, which is receding, and has a brown mustache and beard.
