Honorary doctorates are routinely handed out to random foreign dignitaries or people who donate money to colleges, and do not entitle the bearer to be called "Dr."

I wish. I'm thinking of a friend's boss, a private school headmaster, who insists on waving around his honorary doctorate as "Dr. [name]". The friend, who was teaching there, has an actual proper sweat of the brain Ph.D, and he insisted she should be addressed as "Mrs. [name]". WHAT.
