You won't see this on mainstream TV...

This TV clip is making the rounds worldwide in Spanish speaking nations.

In the clip, Spain's King Juan Carlos orders Venezuelan leader Hugo Chavez to "shut up" as the XVII Ibero-American summit drew to a close recently in Santiago, Chile.

In spite of having his mike turned off, the Venezuelan strongman was continually interrupting Spanish Prime Minister Jose Luis Rodriguez Zapatero, who was defending former Spanish PM Aznar, after Chavez insulted Aznar by calling him a fascist and adding that "fascists are not human. A snake is more human."

Rodriguez Zapatero, who is seeing speaking in the clip, reminded Chavez that Aznar was a democratically elected PM, but Chavez kept insulting and interrupting.

The king is then seen leaning forward and saying in Spanish: "Why don't you shut up?"

The king addressed Mr Chavez as "tu", which is the familiar version in Spanish of "you."

"Tu" is normally used only for younger family members, close friends, and children. In this diplomatic context it is regarded as insulting.

YouTube.com has dozens of rap and reggae versions of the verbal exchange, and the king's words have apparently become a popular ring-tone in Spain.
