You do not need a therapist if you own a motorcycle, any kind of motorcycle!

My great-grandfather, Sam Aykroyd, was a dentist in Kingston, Ontario, and he was also an Edwardian spiritualist researcher who was very interested in what was going on in the invisible world, the survival of the consciousness, precipitated paintings, mediumship, and trans-channeling.

One of my symptoms included my obsession with ghosts and law enforcement - I carry around a police badge with me, for example. I became obsessed by Hans Holzer, the greatest ghost hunter ever. That's when the idea of my film Ghostbusters was born.

I drive a V10 Ford Excursion and I have to tell folks all the time: look I've got five kids and a dog and birds. I would have to have two Lincolns with two V8s, you see, so it would be 16 cylinders.

My parents never had any money. It was cash flow. It flows, and you got your fingers in it for a little while, and it flows away. That's all I know about money. And I don't know, it flows and it's a river, but you can never, ever keep it. As an artist, I can't keep it. But hey, a man who dies with a cent in the bank is a foolish man. So I guess I'm going against the conservators. I'm a spendthrift.

Heaven to me is percussion and bass, a screaming guitar and a burbling Hammond B-3 organ. It's a soup I love being immersed in.

I get really grinchy right up until Christmas morning.
