I came across an article, from February of this year, from when Jim Cummings was selling his mansion home, a steal at $5,195,000 from what the article says. While most of us cannot afford a house like that, the Realtor posted a video tour with Jim as tour guide that is a real treat for us fans.
The full article is archived here.
Great interview with JC
Tour of his house (some really funny parts)
