Yes it’s true, grilled cheese causes muscles! Clearly as seen in this flex-off between Calvin and Mom…..the special way in which Mom’s grilled cheese is prepared causes muscle cells and their protein filaments that slide past one another to grow, producing a contraction that changes both the length and the shape of the cell. Obviously this cheese and muscle miracle is primarily responsible for maintenance of and changes in posture when people eat at Mom’s. The locomotion of the organism itself, as well as movement of internal organs, such as the contraction of the heart and movement of food through the digestive system via peristalsis will never be the same. Is there a Nobel Prize for cheese?
