I love when a sports athlete gets the nickname "Dr." Most people have to study for ten years and spend two hundred thousand dollars to earn that nickname. These guys just need to be really good at the game. You don't see many athletes with the nickname "Dentist" though. I guess that nickname is a little more ominous than "Dr." One such athlete is Julius Erving. He was known as Dr. J. Erving. That's way better than Dentist J. Erving.
His daughter, Alexandra Stevenson is a tennis player. Her last name is different than his due to her keeping her mother's name. Not using her father's name to her advantage didn't seem to hurt her at all. She's competed in Wimbledon and the Grand Slam, and took on Lindsay Davenport, though she ended up losing to her.
