I've done the Parmesean cheese thing before, but even worse, in my haste to clean it up, I vacuumed it and paid for that little mistake later on when I couldn't figure out where that nasty smell was coming from. Yuck!! My vacuum cleaner was never the same after that. And Daffy, I've done the buttermilk thing with a half gallon of Concord grape juice and the kitchen chairs had just been reupholstered in an off-white fabric!
