Guys and gals,

I propose a riddle thread in the same general vein as the ever-popular movie thread. Be the first to answer correctly the riddle above you and then post a riddle of your own. A riddle need not necessarily fit any strict or formal definition of riddle so long as the poster bears in mind that overly complicated puzzles will not be interesting. If nobody has correctly solved the riddle to the riddle writer's satisfaction within two days of its posting, anyone is free to start a new riddle. If you start a new riddle this way, be sure to clearly mark such action with a clever transition such as "Now the real game begins!"

This experiment relies on the honor system: copying and pasting the riddle into a search engine is highly discouraged - use your own noggin!

Let the games begin!

"Completely round is fairly rare.
Bright and shiny when I'm there.
When I'm not, they call me new.
But I'm old. Older than you."
