I've done it too. I took down AA with an 84s. I flopped a flush draw, called a minimum bet and turned a flush. Then called an all-in and took down the AA.

Throughout the rest of the tournament, I never once reminded anyone that I had the big blind and it was unraised pre-flop. I wonder if anyone thought tht I was stupid for playing it, but they didn't mention anything.

Last night I took down AA with KQo. I decided to play it hard, even after I missed the flop. Good thing I was the agressor, I would have never stuck around to see my runner-runner queens.
