The Truths

Justin Edwards - Jackie Chan

- Chan asked for all swearing to be removed from Rush Hour. Found by Lou.

- Chan uses stuntmen in non-action scenes such as when his character is just walking down the street or driving. Found by Alan.

- Chan has said he wouldn't buy Chinese televisions in case they explode. In 2009, he faced a backlash in China after he made a remark to Chinese business leaders about the perceived quality of Chinese-made goods, saying he would buy a Japanese TV instead. While many in the audience applauded his remark, it did not go down well with the public. Found by Lou.

- Chan has taught koi carp to roll over. This can be observed in the following YouTube clip. Found by Lucy.

- Chan is planning a musical based on his own life entitled I Am Jackie Chan. Found by Lou.

Lou Sanders - Blood

- Saddam Hussein had a copy of the Koran written in his own blood. In the late 1990s, he sat with a nurse and an Islamic calligrapher, having a total of 27 litres of blood withdrawn and used to transcribe the holy book. It is now locked away behind three vaulted doors under a mosque in Baghdad. Muslim leaders are unsure what to do with the text, as to write the Koran in blood is forbidden, but it is also considered illegal by many to destroy the Koran. Found by Lucy.

- "House red" is hospital slang for blood, and in particular to the bags of blood used in transfusions. Found by Justin.

- In Ancient Egypt, butchers wore high heels to keep blood off their feet and to avoid slipping. The only other people who wore high heels were members of the upper classes, and people wearing them for ceremonial purposes. Found by Alan.

- According to a study of 200 families, having a younger sibling raises your blood pressure by 5%. Found by Justin.

- Most tropical fish could survive in a tank filled with human blood. Tropical fish require less oxygen than cold water fish, just 2.66ml of oxygen per litre. Fully oxygenated human blood contains 200ml of oxygen per litre. Successfully smuggled.

Lucy Porter - Marsupials

- Napoleon Bonaparte once gave Josephine a wombat to make up for not sleeping with her. Found by Justin.

- 95% of kangaroos are left-handed. They are only the second species after humans to be observed to have a hand preference. Found by Lou.

- There is no collective noun for koalas as they are mostly solitary animals. You do however get a mob of kangaroos. Found by Lou.

- Kangaroos can often be found kissing, as well as hugging. Successfully smuggled.

Alan Davies - Beds

- Hans Christian Andersen was so terrified of being buried alive that he left a note on his bedside table saying: "I only seem to be dead." Found by Justin.

- In 2008, Woolworths once marketed a children's bed called the "Lolita Midsleeper Combi", but it had to be withdrawn after people complained that it shared its name with the 1955 novel by Vladimir Nabokov, in which a stepfather become's sexually obsessed with a 12-year-old girl. A spokesmen for the company said: "What seems to have happened is the staff who run the website had never heard of Lolita, and to be honest, no-one else here had either. We had to look it up on Wikipedia." Woolworths stores shut down the following year. Found by Lucy.

The complimentary service was also trailed in Kensington and Kingston, and was available between 9pm-11pm. Successfully smuggled.
