An investment counselor decide...
An investment counselor decided to go out on her own. She was shrewd and diligent, so business kept coming in, and pretty soon she realized that she needed an in-house counsel. She began to interview young lawyers.
"As I'm sure you can understand," she started off with one of the first applicants, "in a business like this, our personal integrity must be beyond question." She leaned forward. "Mr. Peterson, are you an honest lawyer?"
"Honest?" replied the job prospect. "Let me tell you something about honest. Why, I'm so honest that my father lent me $15,000 for my education, and I paid back every penny the minute I tried my very first case."
"Impressive. And what sort of case was that?"
The lawyer squirmed in his seat and admitted, "He sued me for the money."
