When Spain's King Juan Carlos turned to Venezuelan President Hugo Chavez and said to him, "Why don't you shut up?", he created a commercial monster, the Guardian reports.
The newspaper said those five words have become a multimillion-euro business, selling ringtones, mugs, T-shirts and websites.
An estimated 500,000 people have downloaded the ringtone, generating around €1.5 million, with many companies using an actor's voice instead of the King's.
