Doonesbury by Garry Trudeau for October 28, 1980
Roland: Hi! Welcome to the mysterious world of Ronald Reagan's brain! Home of nearly 30 billion neurons, or "marbles" as they are known to the layman! What wonders away us! The fornix - Reagan's memory vault, storehouse of images of an idyllic America, with 5 cent Cokes, Burma Shave signs, and hard-working white people! The hypothalamus, the deep, dark coils of human aggression, source of Reagan's impulses to send U.S. forces to Angola, Iran, Korea, Cyprus, Cuba, Lebanon, and countless other hot spots! So fasten your seat belts! It's a topsy-turvy funhouse of a trip, but you won't be sorry! Now this.
