I was at work, so I didn't post the answers- but apsinthion was right.

So, you busy little potheads- here's a few more.

1. My thunder comes before the lightning;
My lightning comes before the clouds;
My rain dries all the land it touches.
What am I?

2. I'm where yesterday follows today, and tomorrow's in the middle. What am I?

3. From the beginning of eternity
To the end of time and space
To the beginning of every end
And the end of every place.
What am I?

4. Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I'm double, I'm single,
I'm black, blue, and gray,
I'm read from both ends,
And the same either way.
What am I?

5. The man who invented it doesn't want it. The man who bought it doesn't need it. The man who needs it doesn't know it. What is it?

-and no fair using Google to look up the answers.
