Scrabble Scoring Oddity Nets Scrabble Win for Me

Was playing Scrabble last night with my wife. She was kicking my ass and before I played my last "A" on the board to spell P-A-R for 6 points, and was beating me by about 30 points. As I played out, it was time to count her remaining tiles. She unluckily had a Q (10) left over and an extra piece worth 1 point. She lost the 11 points, but according to the rules, because I used up all my tiles I also get whatever tiles my opponents had left ADDED to my score. So another 11 for me and that was the game. What an awesome way to win! Neither of us will ever leave a high-valued letter on our racks again.
