Heathcliff, who is very skilled with a spoon, is incensed at the lack of fat in his cat food (because Heathcliff is...shall we say...a "butterball"). After disarming both Mrs. Nutmeg and Marcy from Peanuts, he enters a time machine that enables him to travel back to the 1950's, the last time fat was commercially available in large, Quaker Oatmeal-style tins. Back to the future, he gives his cat food a healthy dollop of fat, meaning that it now has much more fat than any cat food Heathcliff has likely ever had.

I hope he dies of cardiac arrest.
