Hello how may I help you? Hi... is this world records help? Sure, how can I help with that? What's the record for the best selling record ever? Hah! The best selling record in the United States is Michael Jackson's Thriller! Oh right! I had that as a kid. Such a classic! Did that help with your query? Yes it did. I think I'm going to have to go buy that again now that I'm thinking about it. Any other world record info I can help provide today? No that's all for now. Thanks. Cheers!
