Hello how may I help you? hi, are you familiar with world records? I am, how can I help with that today? can you tell what the longest thing in the world is? Unfortunately, that query is a little too vague for me to answer. Can you narrow it a bit? i thought there is a record for the longest thing whatever it might be Unfortunately, 'thing' is not a valid world record term which I can help with. ok, how about the longest hair in the world The longest hair in the world measures at over 18 feet long! wow, who does that hair belong to?
