Halloween

Last night my wife and I were sitting at the kitchen table eating a late night snack. Our little black dog was under the table at my wife's feet and our older gray dog was laying beside my chair. I was at the eastern end of our kitchen table facing west and my wife was sitting midway along the horizontal axis facing south. Suddenly a loud pop sounded from the southwesternmost corner in the kitchen followed by a long expelling of (air?). The problem is, theres nothing in that area but a broom. Nothing could be found that even had air pressure. Perhaps we will find the problem was mundane; but we're scratching our heads now.
