I still don’t know if this story is true or not but, my brother’s old soccer coach had a college aged son who was kind of crazy. One night, he had a few friends over for some drinks and someone tried to break in to his house. The guy grabs his shotgun and fires a round in the air to scare the robber off. After that, the guy says to his friends “Do you guys want to see something crazy?”, cocks the shotgun, puts the barrel to his head and pulls the trigger, while thinking he only had one shell left in the gun. I heard this story when I was 8 or 9 and it still freaks me out today.
