Eric is the most irrational of the main characters. Eric is fat and seems to dislike everything except food. He is often the main reason for the plot of each episode. Cartman commonly acts against the other boys. Cartman often insults Kyle for being Jewish and Kenny for being poor. In the earlier episodes, he would also insult Stan for having a girlfriend. Cartman is extremely and seems to be intelligent. However, this is shadowed by his racism and bigotry. Cartman sometimes serves as a speaker for some of Parker and Stone's more extreme commentary about society (three times he has dressed as Adolf Hitler). Cartman hates hippies more than anything else. This is seen in the episode "Die Hippie, Die" which showed his career as a 'hippie exterminator'.
