The answer to this riddle has a hole in the middle,

And some have been known to fall in it.
And sometimes a person may win it.

Though not seen or heard, it may yet be perceived,

Like princes or bees it's in clover.

The answer to this riddle has a hole in the middle,

And without it one cannot start over.
