Many Spaniards were so amused when their king told Venezuela's president to "shut up" that they want to hear the words every time their phone rings.
About half a million people have downloaded a mobile phone ringtone featuring the phrase "Por que no te callas?" or "Why don't you shut up?". That's what King Juan Carlos told Venezuelan president Hugo Chavez during a heated confrontation at a summit in Chile last week.
T-shirts and mugs featuring the words are also becoming a profitable business, and videos of the confrontation have been a hit on the YouTube website.
