He was also arrested for the murders and terrorism of multiple people with Cthulhu, while under the disguise of the Coon, by Kyle, Kenny, Stan, Clyde, Token and Timmy, although they didn't have the authority.

Although he has committed many atrocities and crimes, he has only been arrested six times.

He has been arrested for his mistakenly assumed hate crime, kidnapping Butters, framing Liane for operating a meth lab, being with Stan Marsh on "Whale Whores" (The prison Cartman went to for this assumed crime was Japanese), and incarcerating hippies.

However, his uncanny skill at manipulation, bilingualism, and ability to create elaborate schemes which are often effective imply a surprisingly high intellect, despite his ignorance. Cartman is also a very good leader as a pirate captain, in "Fatbeard", when he convinces all the Somalian pirates to join his crew, and causes so much trouble to international shipping that the United States Navy had to track him down and kill his crew.

Cartman seems to have no problem talking to people and speaking in general. Cartman's shining accomplishment (according to Comedy Central's list of "Cartman's 25 Greatest Moments") came in the episode "Scott Tenorman Must Die", a testimony to Cartman's hidden ingenuity and cunning, as well as the full extent of his cruelty and mental imbalance.

My lusts and fantasies have often brought me online for more kinky sexual activities.

I'm found myself drawn to the idea of controlling women and making them submit to me.

The real reason why Cartman doesn't stay in prison for a very long time is likely because his Mom bails him out, dismissing the severity of the crime.

Another reason why because the town is too incompetent to do anything about it.

Along the same line, in "The Passion of the Jew", he is able to rally all the members of the Mel Gibson fan club to march through the town while yelling, "Wir müssen die Juden ausrotten! But given the fact that it caused a large argument in the middle of the city between his group and some Jews, and given the violent and ignorant nature of most adults in South Park, it would not be surprising if it had turned into violence if allowed to continue.

Cartman was also shown smiling in the background at the argument, as if all was according to his plan.

In several episodes throughout the series, he employs this skill to get what he wants.
