Those pesky flies, always invading your personal space. Time to bring out the fly swatter. No, not the usual flat fly swatter. You need a fly pistol. One that has a bulls eye scoring design that lets you check the accuracy of your aim.
With a spring loaded trigger, you just need to aim and fire. It is a cool way to get rid of irritating flies. You may even get addicted and wish there were more flies around to give you a reason to pull the trigger.
