River Riddle: The Head and Mouth That Never Leave

[foofightergrohl]

A friend of mine asked me this short teaser and I can't seem to figure it out:

At opposite ends are my mouth and my head
I run for miles without leaving my bed

My friend says to think outside the box on this one.

IN White He must be floating that box down a river

Oops, sorry "My friend says to think outside the box on this one" is not part of the teaser. I was just saying that the book my friend got this teaser from says you need to think outside the box to get the answer.

er, I think he just gave you it. It's (in white) a river![/color]

Is it considered "thinking outside the box" if you ask others for help?

Is it smiles?

 

[croxbearer]

is it a telephone?

 

[Jeff Ford]

[michealsmith]

RandallB's answer looks right to me. Explanation in, um...what color works with the new skin again (when I remember where someone posted it, I'm going to sticky the right color so folks will know)? Found the right color:The head of a river is the source, and the end where it flows back into a larger body of water is the mouth. Runs (or flows) for miles without leaving the river bed, which is the land at the bottom of the river.
