The worlds...

I will visit the world's oldest wooden building. So far I have enjoyed the World's longest bench (Kanazawa) and more recently, the World's Largest Frypan, located in Long Beach, Washington.

I am not sure of distinction, but the Siem Reap airport has got to have a leg in for World's smallest airport terminal.

And the world's largest people must be Americans.

And the world's farthest-reaching coffee chain has to be Starbucks.

I would like, however to someday see*
* the world's oldest vomit, the world's angriest couple and the world's most polluted city, if not just to mock, and congradulate myself for being, ultimately, superior to everyone else.
