Riddles in the Dark

The riddles between Gollum and Bilbo were great fun to try and guess while reading.

Anyone have similar type riddles - either others you have heard, or your own creations?

Here is one I came across in a computer game (don't recall which one though)

My tines are short
My tines are gone
Ere my first report

 

Lightning.

Try this:
It occurs once in every minute
Twice in every moment
And yet never in one hundred thousand years.

Lightning is correct.

Alright, here's another

Always run, but have no feet,
Have fork and mouth, but never eat
