King Juan Carlos of Spain finally did something about the biggest, most obnoxious mouth on the world stage.

Venezualean President Hugo Chavez was giving one of his long, boring harangues when he made the mistake of referring to former Spanish Prime Minister Jose Maria Aznar as a "fascist," saying that "Fascists are not human. A snake is more human."

First, current socialist Prime Minister Jose Luis Rodriguez Zapatero quietly told Chavez that Anzar represented the Spanish people and had been freely elected by them. This drew a round of applause from those assembled.

But Chavez couldn't keep his mouth shut:

Chavez repeatedly tried to interrupt, but his microphone was off.

Spanish King Juan Carlos, seated next to Zapatero, angrily turned to Chavez and said, "Why don't you shut up?"

The Venezuelan leader did not immediately respond, but later used time ceded to him by his close ally Nicaraguan President Daniel Ortega to answer Zapatero's speech.

"I do not offend by telling the truth," he said. "The Venezuelan government reserves the right to respond to any aggression, anywhere, in any space and in any manner."
