In an earlier interview with Charlie Rose, Mr. Buffett explained the role he played in Mr. Gates’s engagement in 1994 to his wife, with whom he has had three children. The couple flew into Omaha, where they met Mr. Buffett at Borsheim’s, the jeweler that Berkshire Hathaway has owned for years.
“Look, Bill, this is none of your business, but when I got married, I spent 6 percent of my net worth on the ring,” he recalled saying to Mr. Gates, who at the time had a net worth already well into the billions. “I don’t know how much you love Melinda.”
Mr. Gates can get his jabs in, too. He has said publicly that his daughter calls Mr. Buffett “the man who works at Dairy Queen,” a needle at Mr. Buffett’s oft-expressed love for the company, which he owns, and its signature product.
