Goldfish Crackers

I picked up some toiletries for Austin, so I took them up to his room. A bag of pizza flavored goldfish crackers were sitting on his desk, so I was going to eat a few. There were only ten left, so I finished off the bag. I went down to the kitchen. Austin just came in from work.
Me: I finished off your bag of goldfish crackers, so I was going to get a new one and put it up in your room.
Austin: Don't do that. They keep disappearing up there.

So I hit him with the bag.
