Warren Buffett pokes fun at his mistakes in duet with Paul Anka shown at shareholders meeting

OMAHA, Neb. - Billionaire Warren Buffett poked fun at himself by singing a duet with songwriter Paul Anka to start the Berkshire Hathaway shareholders meeting Saturday.

More than 30,000 people filled an Omaha arena and overflow rooms for the meeting, which always starts with a humorous movie.

One of the videotaped skits featured Buffett and Anka singing a Berkshire-themed parody of "My Way." Buffett referenced in the song a past investing mistake — buying Dexter shoes.

Anka attended Saturday's meeting. The 83-year-old Buffett joked that his pairing with Anka was part of his succession planning, so he and Anka will be available to sing at weddings.

Buffett says someone offered him $1,000 if they both sing or $10,000 if Anka sang alone.
