Two good ol' boys out hunting.
Hunter #1 drops his gun, grabs his chest, and falls over backwards.
Hunter #2 whips out his phone, dials 911, and tells the operator his buddy had a heart attack and is dead.
Operator replies to calm down and check and make sure he's dead.
Operator hears silence followed by a loud BANG!
Hunter #2 gets back on the phone and asks, "OK, now what?"
