"Did you realize that so far, there has only been one trip to the moon and back?
One trip only, over forty years ago.
Two men walked the moon.
Two, like a pair of lovers.
They didn't send anyone to the moon again after Apollo 11.
Although NASA did come up with "Constellation", an ambitious project to return humans to the moon by 2020.

So "I love you to the moon and back" has a very profound meaning.
It means that it's a rare thing.
Infrequent, scarce, sparse, you name it.
For some, it happens only once.
Once."
