All-in with KK?

[PolishSwatTeam]

I was playing a tourney with 6000 people on the net and it was down to about 75 people. I got dealt KK in the dealers spot. All early positions folded and I thought I'd get nothing with my KK, then two seats to the right of me someone went all-in. then the guy in between us called him. I also called...but should I have? (Hellmuth says bet the farm on kings, but do I with an all-in already called?) We all had roughly the same amount of chips. the original all in had AQ suited, the next guy had AA and I had KK...i lost. Should I have folded those cowboys?
