The Rules Continue
Hef was a big fan of establishing rules at the Playboy Mansion. He was not one to enforce the rules though. He let each individual make their own decisions, and if they were caught doing any unsavory behavior, they were removed from the grounds.
Following a Strict Schedule
Many of the standard events at the Playboy Mansion were established within the arbitrary "rules." The only job that the Playmates had was to show up and enjoy themselves, that was it. There were events every single day at the Playboy Mansion, like "Manly Night, "Family Night," "Club Night," "Movie Night" etc. Hef wanted the Playmates to treat these events like they were their jobs, which they were.
