Paul, the octopus who became a pop culture sensation by correctly "predicting" the outcome of as many World Cup matches as he has legs, is retiring. The intuitive invertebrate will "step back from the official oracle business," said Tanja Munzig, a spokeswoman for the Sea Life aquarium in Oberhausen, Germany. Paul then ate a mussel that garnished a golden cup - similar to the official trophy. And what does an octopus retire to, exactly? "Paul will get back to his former job, namely making children laugh," Munzig said.
