Where's the Cheese?

Yesterday while I was preoccupied with other things.. Foster helped himself to the fridge. Today on the menu was cheese. When I came back to real life and discovered the cheese wrapper on the floor and empty (it was a new block), I asked Foster "where's the cheese Foster?". All he could say was "ummmm" with his finger on his chin and then he would point to somewhere in the house (every time it was a different spot). I finally found the hidden cheese under a pillow on the couch. Do they have 3 year old refrigerator locks?
