For centuries, Hindu women have worn a dot on their foreheads.
Most of us have naively thought this was connected with tradition or religion, but the Indian embassy in Australia has recently revealed the true story.
When a Hindu woman gets married, she brings a dowry into the union.
On her wedding night, the husband scratches off the dot to see whether he has won a KFC store, a BP service station, a phone shop, a taxi cab, a brothel, or a Australian passport for life.
If nothing is there, he must remain in India to answer telephones and provide us with technical advice for Telstra.
