Anna Nicole Smith Is Kicking Herself Turns out Warren Buffett is a funny man. Here's an observation from NPR's Robert Smith, who was on the scene today when Buffett gave letters to the Bill and Melinda Gates Foundation and four other charities pledging to give them all his money: When Warren Buffett was signing the letters today, he said he had to check the names twice. "I wanted to make sure I didn't write one that says 'Dear Anna Nicole Smith,'" he joked. Buffett also mentioned that he accidentally left the letters in a PBS studio this morning after being interviewed by Charlie Rose. Rose rushed down to the street to return the gift letters. Buffett told Bill and Melinda Gates that he "made sure that he hadn't crossed out their names and put in 'Charlie Rose.'"
