Behind the Laughter

 * The cereal's name is a reference to former First Lady (1929–1994), wife of President . When she re-married (to shipping magnate ) five years after Kennedy's assassination, she was nicknamed "Jackie O" in popular culture.
 * Both during and after Kennedy's presidency, Mrs. Kennedy was known for her independent and widely respected fashion sense (particularly for the pink suit she was wearing the day JFK was assassinated), alluded to by the cereal box's color scheme and promise of stretch pants.
