Bad Beat

Hello,
I know everyone hates bad beats but this one needs to be shared. I was playing at Full tilt the other day and I was holding pocket kings. The flop comes out K K A. This put me in total control. I checked but then someone raised so i reraised. He called the next card was a 2. Then he went all in and he showed me Pocket Aces ( he has a fullhouse). But on the last card I changed from happy to pissed when it was an ace giving him the better quads.

That is a bad beat my friend, just about the worst I figure.
