My friend had AA in a tournament, and 2 other guys went all in with TT and TT preflop. That in itself isn't so messed up, other then the fact that one of the TT beat my friend's AA with a 4 card flush draw to knock him out of the tourney (he was covering 1 flush card for each player, which meant there were only 2 4 card flush possibilities).
Calculating the odds with a poker hand calculator, the AA had a 94.83% chance of winning on the flop, while both TT had 1.18% chance to win the pot.
Just to put it in comparison with the OP hand, AA vs KK vs QQ, AA is a 66.38% winning favourite versus 17.67% for KK versus 15.56% for QQ.
