As a child, he played games alone due to having only a few friends in the neighbourhood. He had a knack for drawing privates and ogled at the beauty of them all.
A natural born, promiscuous psychopath, Joseph was also a serial womaniser, slipping about five real life women celebrities throughout his lifetime, without success all the time. That included Enid Markey in 1918, Agnes Moorehead in much of the 1920s, Maureen O'Sullivan in 1931, Teala Loring in much of Wold War two and Elizabeth Montgomery in 1959. Luckily, they all escaped Diamond Joe's wrath.
Being both a successful and a corrupt politician who switched sides so frequently, his behaviours, political adventures and scandals were so brazen that they drastically changed the way some modern neurologists think about psychopathy in actuality.
He slipped all five of Clovis and Joe's nannies during the 20 years of his mayor status in Springfield, as well as five other mistresses, including a fellow younger mistress herself - his only wife, the half-Mosuo Rose Yang, during his whole adulthood.
The strange behaviours were still rocking all of America until his ironically fascinating disappearance in 1961 and thereafter incredibly #metoo feminist murder by Rose Quimby, with the help of her best friend (The third nanny Marge Pendleton) and - ironically - the whole Cassadine Mob, who currently terrorise Port Charles and beyond. They all murdered him at the dying Springfield mall in order for Joe and Clovis to survive.
They covered him with blankets, when they dumped him into a sand trap at the back nine a year later. It was found nine more years later, in 1971.
