If you won the lottery, what would you do with your millions?
Keep very quiet about them.
Lawrie Bradly, Surrey Hills, Victoria, Australia
• Stick it in the bank until I’d recovered from the shock.

Meg Sutton Benseman, Auckland, New Zealand

At what point does madness become brilliance?
Look to skits by the Marx Brothers, Monty Python and, as the French say, Le Grand Jerry Lewis.
Richard Orlando, Westmount, Quebec, Canada
• The link between madness and genius tends to be exaggerated. People who have psychotic illnesses may be ordinary or brilliant, and they usually improve with treatment. Not all madmen are geniuses and not all geniuses are mad.

• When a goalkeeper dives head first at the feet of a rampaging attacker and grabs the ball.
Charlie Bamforth, Davis, California, US
• At the same point where brilliance ceases to be sane. That is, if you conceive of intelligence as a line, and it would be madness to do so.
Bryan Smith, Sweaburg, Ontario, Canada
• When it has an apparently beneficial impact upon others.
Philip Stigger, Burnaby, British Columbia, Canada
• As Einstein pointed out, the only difference between genius and insanity is that genius has its limits.
Ursula Nixon, Bodalla, NSW, Australia
• When the person concerned begins to shine.
Avril Taylor, Dundas, Ontario, Canada
• When David took on Goliath.
Rhys Winterburn, Perth, Western Australia
• When the lunatics who have taken over the asylum present themselves with honorary doctorates.
Neil Johnson, Birmingham, UK
• When, like Christopher Smart, you consider your cat Jeoffry.
E Slack, L’Isle Jourdain, France
We all want to live it up
Will there ever be a time without construction sites?

Mac Bradden, Port Hope, Ontario, Canada
• No, because we all like living it up.
David Tucker, Halle, Germany
Depends on what country
Is it possible to reason with fanatics?
In some countries, we cannot know, as it’s too dangerous to try.
Ralph Bosman, Osaka, Japan
• The man on the Clapham omnibus has long given up. Take a cue!
Norman Harries, Lethbridge, Alberta, Canada
