7. Fatty Doo Doo
Episode: 'Raising The Bar' (S16) When Kyle forces Cartman to realise that he is indeed fat and not big boned, Cartman decides to embrace his weight by buying a mobility scooter to get around. Everywhere. He won't even go to the school toilets without having a disability ramp installed. He also becomes an advocate for the obese, prompting lawsuits against BestBuy and anyone who doesn't have doors wide enough to accommodate him. Kyle and Token set about filming a documentary to expose Cartman, but Token turns it into another enabling device for Cartman's monster ego. Fatty Doo Doo is born and lays the smackdown on Honey Boo Boo. While this is not necessarily one of Cartman's most harmfully evil moments, it just goes to show how his ego can get in the way. All he wanted was to take a simple dump at BestBuy, you guys.
