Saber/Conocer. What's the rule?

Question

I want to understand when to use saber and when conocer. I have studied lots of sentences but I cannot get the difference. So is there a grammar rule to understand it?
Thanks a lot

I'll take the opposite position (that way, _one_ of us will be right) and perhaps someone will come along and provide an authoritative opinion.

Oh come on! Didn't we start this thread with Lazarus actually agreeing with both of us? Why ruin a record?
