He may not sing, but you can have lunch with the Oracle of Omaha

OMAHA, Neb. -- Bidders on eBay will have the chance to win lunch with billionaire Warren Buffett next month.

Last year, two investors paid $650,100 for the chance to have lunch with the chairman and CEO of Berkshire Hathaway Inc.

The auction benefits the Glide Foundation, which provides social services to the poor and homeless in San Francisco.

This will be the sixth year Buffett auctions a lunch on eBay and donates the proceeds to the foundation.

This year's auction will begin at 7 p.m. Pacific on June 22 and end at 7 p.m. Pacific on June 27.

The winner and up to seven friends will dine with Buffett at the Smith & Wollensky steakhouse in New York City.
