A few 'juicy bits' of Katherine Losse's Facebook tell-all, "The Boy Kings", via The Daily Beast:
"On Mark's birthday, in May 2006, I received an email from his administrative assistant telling me that it would be my job that day, along with all the other women in the office, to wear a T-shirt with Mark's picture on it." The men, on the other hand, were told they would be wearing Adidas sandals all day. "The gender coding was clear: women were to declare allegiance to Mark, and men were to become Mark."
Casual Friday never looked so twisted.
