Not fast enough

I had "Find a way to keep the fridge and freezer locked" on my list of things to do, but I didn't get to it fast enough. I came downstairs after changing Jon's diaper and found that Ben helped himself to a snack.

He proudly showed me what he called his "cheese block" but was actually a frozen stick of butter. Yes, he was chowing down, enjoying every bit of the frozen grease bar ON MY COUCH!!! Needless to say, the rest of the stick went into the trash and I rigged the appliance so they can't get in it (I hope.)
