According to the Hasbro corporate history, George Parker — the founder of Parker Bros. — took more time to die than your average opera character:
"Parker's death came around the time when his company introduced three of the most successful board games in their history -- SORRY!® (1934), CLUE® (1949), and RISK® (1959)."
