What's Your Calling In Name-Life?

Throughout the years, I have met people through their professions, people whose names define their work. Here's a sample, but with a twist: See if you can find out which one I made up.

The woman who cleaned our house when I was in high school: Mrs. Sloppy.

My mother's proctologist: Dr. Colon.

The orthopedic surgeon who operated on my knee: Dr. Hopp.

My regular dentist: Dr. Nash.

Honestly, three out of the four are actual professionals in the indicated field and their names. Any guesses as to which is fiction?


Edit for the Answer 5-6-2008

ANSWER:Two out of three guessers got it right. Dr. Colon (spelled Colón, but pronounced by Mom as ":") was not Mom's proctologist, but was her gynocologist. I used to joke that he just missed his calling.

Oh, and not only was Mrs. Sloppy Mom's house cleaner, her first name was Ida.
