While out in the woods, Cartman discovers a strange creature. Some government scientists tell the townspeople that the creature is a Jakovasaur: a prehistoric animal thought to be long extinct. Soon afterward, the first Jakovasaur's mate turns up in South Park, and the town immediately begins trying to get them to breed so their species can recover. This, however, leads to a bigger problem: the Jakovasaurs turn out to be so annoying that nobody (except for Cartman) can stand them. Written by Jean-Marc Rocher <rocher@fiberbit.net>

Cartman's mom smoking crack!
25 October 2008 | by (Canada(Montreal,Quebec)) – See all my reviews

A lot of people seem to dislike this episode.While it is not my favorite, it does have some pretty funny scenes, such as when we see Cartman's mom smoking crack and having sex with the two men who are trying to locate the jackovasaurs(jack-off-asaurus).These "Jackovasaurs" are a breed of dinosaur where they find the last one.They then find another male one, and they basically repopulate their species.The townspeople like them at first but then they see how annoying they are.Cartman however really likes them and thinks they are funny.The townspeople try to get rid of these annoying dinosaurs.This episode was not the best but it did have some great parts.
