Oprah Winfrey has worked her magic as she made amends with David Letterman on Thursday. Her appearance on his show was her first in 16 years, which came after years of on-air pleading by Letterman. The result: the highest ratings for CBS's 'Late Show' in more than 11 years, or an average of 13. 5 million viewers and a 4. 4 rating in the adults 18-49 demographic, according to preliminary estimates from Nielsen Media Research. Winfrey's appearance marked the fourth-highest rated 'Late Show' broadcast since the show premiered on CBS in 1993 and the most-watched episode since the February 1994 night when Letterman followed CBS' coverage of the winter Olympics ice skating finals featuring Tonya Harding and Nancy Kerrigan.

China to host world toilet summit and first ever toilet exhibition to showcase their recent advancements in potty technology. The World Toilet Expo being held in Shanghai from May 8th to 10th, will feature China's plans to make relieving oneself a more comfortable, convenient experience - specifically for tourists visiting the fashionable city. One such addition would be a 24-hour toilet tracker phone line people could call to locate the nearest public facility. "It's expected to solve the long-lasting problem that tourists, cab drivers and people unfamiliar with the city cannot find a toilet when they need one," Han Yurong, a Shanghai Public Sanitation Bureau official, was quoted by state media as saying. Beijing, home of the 2008 summer Olympics, has added high-tech, self-cleaning toilets near major tourist sites in preparation of the event - adding that they will keep the toilet paper fully stocked. Shanghai plans to revamp 500 of its 3,900 public toilets this year, build new ones and reserve two thirds for women. Today, most of China's public toilets are squat-style pits with no running water, toilet paper, or hand-washing facilities.
