This is a question that has Boggled my mind all day can you help me?
O.k. say I had a Dark Garyados as my active pokemon aginst a Snorlax.
Snorlax knocks out Dark Garydos but Flips and paralyzes him on the turn
he knocks him out! Dose then A)Snorlax gets knocked out because of Dark
Garyados's PP or B) stay alive because he paralyzed him. Plz help
me!!!!!!!!!

Great question.  Looking though the rules very in depth gives the answer to this question.  To know, you have to understand the order things happen as it pertains to attacking

1) damage is applied
2) effects are applied
3) check for Knock-Out

This is simplified, but the oder they go in.   So, looking at that, we now know that the Gyarados will be paralyzed when it goes to the discard pile, and will not use Final Beam.
