Government officials also heard stories of Ruby's eccentric and unstable behavior. He sometimes took his shirt or other clothes off in social gatherings, and then either hit his chest like a gorilla or rolled around the floor. During conversations, he could change the topic suddenly in mid-sentence. He sometimes welcomed a guest to his club, but on other nights forbade the same guest from entering without giving an explanation. Ruby was described by those who knew him as "a kook", "totally unpredictable", "a psycho", and "suffering from some form of disturbance".
