Ninja babyproofing, part deux

I have finally found a refrigerator lock. I put it on the fridge 2 nights ago and we have had 2 mornings of waking up to a clean kitchen. Coincidence? Perhaps. I think, however, that the lock stops the little Christmas elves from raiding our food stuffs. I have previously been waking up to 3 or 4 yogurt cups, opened and half eaten. Now, I just need to find a way to lock the dishwasher and stove.
