English- we are in the computer lab. 5 minutes into class. Class dick leaves to go to bathroom. I turn his computer screen sideways (command on windows is control+alt+arrow key, use that as you will). He comes back. Starts poking random buttons, trying to get screen back to normal. Continues to do so throughout the next 40 minutes, can see him getting angry. 5 minutes until bell, he goes and asks the teacher for help, explains the problem. While he is up, I put screen back to normal. Teacher comes and looks at screen, thinks he is making stuff up to avoid work. He never suspects me. Not that dumb, but fun.
