AA vs AA vs KK vs KK

This is a new incredo hand. Sahara 11pm tournament tonight, four folks got all in pre-flop. They flip their cards over and we see AA, AA, KK, and KK. I've seen 4 aces on the flop/turn. I've seen lots and lots of AA vs KK vs QQ. I've flopped a royal flush. But this is a whole new level of improbability.

Course the guy who folded 74 claims he woulda won the pot.
