Just what is it that makes Artists give such long titles to their Works?

Damien Hirst's The Physical Impossibility of Death in the Mind of Someone Living

Richard Hamilton's Just What Is It That Makes Today's Home So Different, So Appealing?

Marcel Duchamp's The Bride Stripped Bare by Her Bachelors, Even

Do long titles make works seem more witty? Poetic? Impactful? Or are artists simply too darn bored? I wonder.
