Shoot my art teacher.
I was in 8th grade, and I went to a catholic school, so shit was bad, so I created the COD game, where me and my friends would pretend to go around and shoot shit/people and blow shit up. So when we were walking in from recess, I got out my glasses case, went up to the side of my art teacher, and shot him in the head and laughed my ass off about it right in front of him. All of us got called into the office and they yelled and said they could call the cops, lol on that one, but yeah.
