Calvin and Hobbes by Bill Watterson for April 29, 1986
Calvin: The tyrannosaurus lumbers across the prehistoric valley... The terrifying lizard is three stories tall and his mouth is filled with six-inch chisels of death! With a few mighty steps, the dinosaur is upon a tribe of fleeing cavemen. He devours then one by one! Aarrgh! Aaieee! Aaughh! Mom: Calvin, eat your popcorn quietly!
