Flopped full house loses to runner-runner, huge pot

After suffering bad beats all day yesterday, including losing all three times I had pocket aces to ridonkulous hands, I thought today's action would have to be kinder. Think again.

First hand of the day I'm in the BB with 77. MP raises, I call, and five players see the flop: 7-5-5. Sweet. I bet out, and the table goes nuts and caps. Turn is a 9. I bet out again, and with four players it's capped again. River is another 9. Pot is capped. Original raiser turns over 9-8s!! Holy schmoly, over 80BB in the pot.
