The widow of producer Aaron Spelling is placing “The Manor” in the exclusive Holmby Hills neighborhood on the market for a jaw-dropping $150 million, making it by far the most expensive home for sale in the U.S.

Candy Spelling told The Associated Press that she let her dog Madison, a soft-coated Wheaten Terrier, help pick out the best real estate agent for the task. She had her security bring the dog into the room every time she met one of the candidate agents and watched how the dog reacted. If Madison didn’t like them, Spelling crossed them off the list. [via]
