Finally, someone has explained this.
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 High Commission in London , 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's won a corner shop, a petrol station, a curry restaurant, a taxi cab or a motel in the United Kingdom. If nothing is there, he must remain in India to answer telephones and provide us with computer technical support.
