Then there was that concoction Cartman made on the Fat Camp episode...

Lets see... 2 frosted pop tarts, a stick of butter and powdered chocolate I think. He toasted the pop tarts, powdered the stick of butter with the chocolate, then put the butter between the toasted pop tarts and it all squished out (must have kept it out of fridge for it to be soft... or maybe the hot pop tarts softened it...)

Then he goes out to watch TV to be confronted by everyone about him being fat...
