No doubt about it. Not a good move to piss him off.Stewie against Cartman? That's like bringing the canary to the cat. If Cartman can fool Scott Timmermann into eating his own parents, Stewie wouldn't stand a chance. Cartman is too diabolical, even for Football Head.
You underestimate Stewie. He is a diabolical genius. He will eliminate Cartman with a weapon of mass destruction that he invented himself.
No one in South Park can withstand Stewie Griffin. Except for Ike Broflovsky.
No doubt about it. Not a good move to piss him off.The thing is, Stewie wouldn't care if Cartman made chili out of Peter and Lois. He would beat up Cartman just to lick the spoon!
If it comes down to Cartman vs. Stewie, my money is on Stewie.
