Wanna bet? Gambling on the Games

What are the odds of a UFO sighting during the London Olympics opening ceremony? Or of the final torch bearer tripping as they ascend to light the flame? Or would you prefer a more traditional wager on the battle for gold between Russia and Spain in synchronized swimming duos?

London betting houses will offer odds on almost anything, including all 26 sports at the games, from the 100m dash to fencing, from diving to soccer. The industry expects to handle a record 100 million pounds ($155 million) in wagers during the July 27-Aug 12 competition - even some pretty outlandish parlays.

"We try to cater to most people's tastes," said Joe Crilly, a spokesman for William Hill, a gambling house that encourages punters - the UK term for gamblers - to contact them with any bet they can dream up. They also offer online gambling in 182 countries, though not in the United States or in other countries where it is prohibited.
