24 + 2 90 person knock out

Down to 30 or so players, I have 8000 chips. I get KK. Raise. Guy about the same size chip stack as me goes all in. He has A 9 off suit. WHAT THE F*CK? Are you serious? You risk your tourney life on A 9 off? Of course the river happens to be an ace? AT this point it is painfully obvious I am on a sh*t list at FT. There is no way that random does not EVER allow my better hand to hold up.
