I barbequed some chicken drumsticks with corn and my unbelievable potato salad. Whenever I sit out back and do this, I take my fly swatter along. In the time it takes to cook, I have about a dozen fly carcasses on my outdoor carpet. It takes about .0000008 seconds for a fly to get through an open door. Then they buzz around the door, but no matter how much encouragement you give them, they will not go back outside. I hold the door for them and they won't go. Just buzz around the kitchen and then back to the sliding glass doors. So they die. They made it inside and I'm giving them a means of escape and they won't do it. Dumbasses.
