Hello how may I help you? Is this a repository of World Records? I am a bot designed to provide you with current world record information. What would you like to know? What is the longest thing in the world? I'm sorry, but this request is too vague for me to search the database for. Please try a new search. That is not very helpful. Surely there is a listing for the longest thing? Is it a piece of string, or a fence, or a railroad? I have many listings for length, but the database is rather extensive. Please refine your search, or try a new one. Or what? Is it the world itself? The query "Length of..." is too vague for me to handle, and must be refined. Search for the longest measurement done and that is the thing that is the longest. Is there a World Record for the least useful bot? Unfortunately, the request timed out. Please refine your search, or try again.
