I was changing a light bulb over Groucho Marx's bed, so I took my shoes off, got on his bed and changed the bulb. When I got off the bed he said: 'That's the best acting you've ever done.

I believe in evolution and I think when it comes to business and the roots of business and the fundamentals of business, I don't think that ever changes. I think the idea of change is an illusion, but in nature it's necessary to change and perhaps business is a part of nature. I'm not totally sure.

Groucho Marx, in his later days, gave me the best review I've ever had and probably will ever have. I changed a light bulb over his bed, and when I came off of his bed with the used one after putting the new one in, Groucho said, 'That's the best acting I've ever seen you do.'

I do know people and there are people in my family who have had Alzheimer's and dementia, and I appreciate the importance of communication and having contact with them. Communicating is an interesting thing with a condition like that. Sometimes it's difficult to communicate. If the brain becomes atrophied or certain channels of the brain become atrophied, then contact is what becomes really important.
