■ Guinness gets about 50,000 record inquiries a year. Last year, Guinness reviewed about 2,000 claims in the United States alone.
■ American Ashrita Furman holds the most records with 164, including most eggs crushed on his head in one minute (80) and number of sit-ups in an hour (9,628).
■ Not every record claim is verified in person. Other evidence — witness statements, photos, media coverage — is often accepted instead.
