If it were a fight to the finish between the Sta-Puff Marshmallow Man & Frisch's Big Boy, who would win?

Frisch's Big Boy would probably go down in the first round because the Stay Puft Marshmallow Man would jump on him and almost smother him (plus, the sight of him would give anyone a damn fright) but then, in round two, Big Boy would seize his chance, and retaliate with a hot pumpkin pie to the face ... and the Stay Puft Marshmallow Man wouldn't stay puffed for very long after that!
