Years ago, from Mad Magazine (from memory)

WAR (sung to to the tune of More)

War, helps to keep the population down.
War, means less people in a crowded town.
War, let's us try out new artillery.
War, gives our soldiers foreign trips for free.

War helps the USO.
Yes, War brings a Bob Hope show.
Yes, War gives us lots enjoyment
And it cuts down unemployment.

War, gives us heroes who are strong and good
War, gives us John Wayne films from Hollywood

War, gives our TV newscasts more
Scenes of blood and death and gore
And that's what living color's for!
