DANTHURS: I realize you've said "check both ends of your battery cables. If they corrode they will still let enough threw to turn on lights, but not enough amps to turn over the starter. So check both ends of both cables. Clean them good and put them back on."

However, I have a question about this logic (as I am experiencing the same issue):
If this is actually the case, should I still be able to jump-start the car?
Occasionally I'd come to the car and there would be no power -- completely dead. I discovered that it is probably (or at least initially) a connection issue, as when I first went to jump it, I just wiggled the cables going to the (+) side, and suddenly I had full LIGHTS/accessories and the car would start.
this problem proved intermittent and I just put it off for about a month. (i know, i know.) In the span of the month, there were probably 4 times that I had to go under the hood, wiggle the (+) cable, and it would work.
Well, as of this morning, I have full lights/accessories in the car, but it won't turn over. I get a singular loud "click" off the starter (as opposed to a frantic "clickclickclickclickclickclick" that would allude to a trashed starter), but no rev or anything that would allude to a fuel/spark problem. And I can tell it'* pulling on the battery, but it won't actually turn over.
So, I tried to jump start it - nothing. I left my dead 94 Bonneville hooked up to my running 99 Grand Prix for 20+ minutes, came back - same.
I'm hoping it'* a dead/dying battery or corroded cable - but the matter of it not wanting to jump/charge off of my other car has me thinking it might be a starter/relay/something worse.
Thoughts on this??
