Hello how may I help you? I'd like to know what the best selling record of all time is. I can help with that! The best selling record of all time is Thriller Oh! Michael Jackson, right? Yes! Can I assist you with any other world records today? Was that the best selling record of all time in the US or the whole world? Thriller is the best selling record in the whole world. The best selling album in the US is Adele's 21 I'm so surprised, I thought it would be Thriller in the US and maybe something else worldwide. Yes, that is true. Anything else today? No, thanks for all the facts. No problem!
