- It's "feel the burn", which was a catchphrase popularised by Jane Fonda, who released a number of fitness videos.
- It's epilepsy. Chopin's tendency to drift off while at the piano was interpreted by his partner George Sand as "the manifestation of a genius full of sentiment and expression". But Spanish researchers say Chopin's hallucinations may have been due to temporal lobe epilepsy.
- It's digging. Linhenykus monodactylus, which stood just 60cm tall and weighed about the same as a large parrot, may have used its dino-digits to dig into insect nests.
- It's the iPod and other electronic gadgets. Democratic State Senator Carl Kruger, who is proposing restrictions, has been trying since 2007 to ban the use of mobile phones, iPods and other gadgets by pedestrians in major cities while crossing the street. He says he has sponsors in the state assembly.
- It was Tim Henman. In the letters "Salinger describes his day-to-day life, going on various coach trips around the States, chatting to people on these excursions, visiting restaurants, art galleries," says Professor of American Studies Chris Bigsby.
- It's South Korea. "In South Korea teachers are known as 'nation builders'. Here in America, it's time we treated the people who educate our children with the same level of respect," Mr Obama said.
- It's Florida Keys. US authorities and local residents were puzzled when the piano appeared on a sandbar in Biscayne Bay, Miami. It is located a short distance from the Keys.
