I've also seen AA v AA on the Final Table of an FTOPS Event (I believe it was the $2,500 buyin, or $1,000 buyin?.. anyways it was a big one).
AA won flopping two spades & then runner runner spades & left the other stack crippled (bustinbusters was the crippled stack). The two players were sitting 1st & 2nd with 6players left, difference between 6th & 1st was over $300,000. Now that would be soul-crushing for me! (I had the handhistory saved but can't find it right now.... maybe on my other puter.. I'll have a look for it).
