A look at some of the more unusual and wacky stories making headlines across the globe.

SIRI SAVIOUR

A Tennessee teenager is alive, thanks to Siri. Sam Ray, 18, says the voice recognition service on his iPhone - famously named Siri - called emergency dispatchers after his truck fell on him while he tried to make repairs.

Mr Ray told media outlets that a jack collapsed, pinning him under nearly 5,000lb of metal in a location where he could not be easily seen or heard. He said he was trying to get free when he heard Siri activate. He said: "I said 'Call 911,' and that was all it said."

Rutherford County dispatcher Christina Lee said she first thought it was a mistaken pocket-dial, but then she heard his screams for help and sent crews, who rescued him. Mr Ray and Ms Lee have met for the first time after the July 2 incident.

CAKE MISTAKE

A 21st birthday cake came decorated with a blind girl after an autocorrect mistake.

Marie Seggie accidentally asked her friend to make a cake for her daughter with a "wee blind girl" on top, instead of a "wee blonde girl".

Her daughter Emily tweeted a picture of the cake, saying: "My mum ordered a cake for my sister's birthday and asked for a blond girl on top but it autocorrected to blind and we got this."

MILK TEETH

Adding milk to tea actually stops teeth becoming stained, the Daily Mail reported.

It was even more effective than whitening toothpastes, and was as equally good as some bleaching products, researchers found.

"Tea is the second most consumed drink in the world, and the way it's processed affects how teeth are stained," said Dr Ava Chow, of University of Alberta's School of Dentistry.

POPES PLAGIARISED

A leading Peruvian newspaper says it will no longer publish columns by Roman Catholic Cardinal Luis Cipriani after he was caught plagiarising two popes.

The unattributed texts were found last week in two columns that El Comercio published, one earlier this month and the other in May. They were discovered by reporters at the news website Utero.pe, which determined that Peru's cardinal had lifted texts from Paul VI and Benedict XVI.

El Comercio ratified the findings, saying on its website that Cipriani had penned his last column for the paper. It deleted the two columns from its website. The conservative 71-year-old cardinal apologised on a radio programme and asked listeners to "pray that we pastors are always true to the teachings of the church".

WILD WEEK

A 70-year-old man survived a week in the woods after he fell while out for a walk in western New York.

Donald Farrell was found on Sunday morning amid trees and tall weeds about two miles from his home in the Livingston County village of Avon, 20 miles south of Rochester. He was found by his cousin on the cousin's property, officials said.

Mr Farrell had last been seen going for a walk on the morning of Sunday August 9. He was taken to a Rochester hospital where he was treated for dehydration. Police said he is in "excellent condition" considering he had been exposed to the elements for a week. Mr Farrell told officials that he fell while walking and could not get back up.

MID-AIR COLLISION

A flying instructor and his pupil were left shaken after a buzzard crashed through the windshield of their Cessna, the Daily Mail reported.

Ian Weston, 52, who was supervising qualified pilot Simon Edwards on a refresher course, said: "It all happened in a nanosecond.

'We felt a rush of air and loads of feathers with bits of broken Perspex. Then we looked up and saw a gaping hole in the cockpit and a buzzard lying on the parcel shelf behind us. It was quite frightening really."
