U.S. President Barack Obama recently gave an interview on "The Tonight Show With Jay Leno".
The kind of language which Obama not normally associated with a US President is spreading like wildfire online. The clips are from the audiobook version of Obama's autobiography, Dreams from my Father, which is read by the president himself.
They include quotes attributed to a schoolfriend of Obama's who had a rich vocabulary which is reproduced in graphic detail in the book.
US actress April Winchell has posted audio clips of President Barack Obama reading some of Ray's fruitier expressions on her website, www.aprilwinchell.com.
She writes: "You're about to hear the President of United States using language that would finish Cheney off once and for all."

The White House declined comment.
Several of President Obama’s Kenyan relatives went to Washington, DC, for his inauguration, but George was not among them. He lives in Huruma with extended family.
Media reports about him surfaced over the summer, after a magazine article said he lived in a shack and earned a dollar a day. George Obama has called the reports insulting.
“I’m proud of how I live,” he said in an interview over the summer. “[The media] are tarnishing the family name.”
He also said he was studying to be a mechanic and works with a local youth group in Huruma.
In President Obama’s book Dreams From My Father , he describes George Obama as “a handsome, roundheaded boy with a wary gaze”.
George is the youngest of the senior Obama’s seven children, born six months before his father died.
A US toy company is renaming its Malia and Sasha dolls after a complaint by First Lady Michelle Obama. The dolls, originally called Marvelous Malia and Sweet Sasha, will be named 'Marvelous Mariah' and 'Sweet Sydney'.
Dollmaker Ty Inc says it changed the names after Mrs Obama said that using her daughters' names was inappropriate.
It had said the dolls were not modelled on the Obama girls, but the names suited dolls they were already making."We appreciate the company's response to this matter," said Mrs Obama's press secretary, Katie McCormick Lelyveld.
Barack and Michelle Obama have two daughters: Malia Ann was born in 1998 and
Sasha was born in 2001. Sasha is the youngest child to reside in the White House since. Malia and Sasha attend the private Sidwell Friends School in Washington, DC, the same school as attended by Chelsea Clinton, Tricia Nixon Cox, and Archibald Roosevelt.
The dolls were part of the Ty Girlz Collection, and went on sale in January, joining others in the same range called Bubbly Britney, Lucky Lindsay and Precious Paris.
President-elect Barack Obama's speeches are proving a best-seller in Japan -- as an aid to learning English. An English-language textbook, "The Speeches of Barack Obama," has sold more than 400,000 copies in two months, a big hit in a country where few hit novels sell more than a million copies a year. Japanese have a fervor for learning English and many bookstores have a corner dedicated to dozens of journals in the language, many of them now featuring the new US leader's face.
