More things we learnt in 2005.

From the BBC.

11. One in 10 Europeans is allegedly conceived in an Ikea bed.

12. Until the 1940s rhubarb was a vegetable. It became a fruit when US customs officials, baffled by the foreign food, decided it should be classified according to the way it was eaten.

13. Prince Charles broke with an 80-year tradition by giving Camilla Parker Bowles a wedding ring fashioned from Cornish gold, instead of the nugget of Welsh gold that has provided rings for all royal brides and grooms since 1923.

14. It's possible for a human to blow up balloons via the ear. A 55-year-old factory worker from China reportedly discovered 20 years ago that air leaked from his ears, and he can now inflate balloons and blow out candles.

15. Lionesses like their males to be deep brunettes.

16. The London borough of Westminster has an average of 20 pieces of chewing gum for every square metre of pavement.

17. Bosses at Madame Tussauds spent £10,000 separating the models of Brad Pitt and Jennifer Aniston when they separated. It was the first time the museum had two people's waxworks joined together.

18. If all the Smarties eaten in one year were laid end to end it would equal almost 63,380 miles, more than two-and-a-half times around the Earth's equator.

19. The = sign was invented by 16th Century Welsh mathematician Robert Recorde, who was fed up with writing "is equal to" in his equations. He chose the two lines because "noe 2 thynges can be moare equalle".

20. The Queen has never been on a computer, she told Bill Gates as she awarded him an honorary knighthood.
