A gentleman by the name of Bob Dixon.  Don't ever forward his calls or give out any information.  Once he has them, he will call you relentlessly, like every damn day.  I've tried telling him if he left a message, then he needs to wait for a return call.  I've tried just hanging up on him (lost the call in transfer, oops!) and he doesn't get the clue.  Works for an investment firm and absolutely insists that you should review your retirement plan with him.
