Philip liked to collect teacups, a little-known fact. An angry wife of his started tossing pieces of his sizable teacup collection from an upstairs window as he approached his house, and he scurried back and forth across his lawn to catch as many of them as he could.
Dick was also deeply attracted to clinically insane women. In fact, after brief stints of psychiatric hospitalization, he would usually walk away with the phone numbers of female patients he met during his stay.
His heavy use of amphetamines only accentuated his legendary paranoia. For a while, he disconnected from many close friends, convinced they were undercover agents sent to spy on him. Eventually, he shook that delusion and was somewhat depressed to realize that the government really wasn't out to get him after all.
