My optimistic outlook on life is to sort of be positive and take everyone at face value.

I am very much into the paranormal.

I've always been a big fan of the Yeti, simply because I have an affiliation to Everest - who was the New Zealander, Sir Edmund Hillary, the guy that conquered it.

I've never really been into ghosts or spirits, and I've only had a couple of those kind of experiences.

When I do the Edinburgh Fringe Festival, I always go across to Loch Ness and stay there.

You've got to have a likeability factor, I think, in your comedy characters. If the guy's really, really funny but you just don't like him or her, then you're never going to root for them.

I think Psycho Sam is closer to the real me in some ways which is frightening to admit, but I guess... I mean, I'm definitely into the paranormal.
