Came At You From The Left-Field

(In physics, during a quiz on magnetism earlier in the semester, I realize a couple kids who sit behind me cheat off me for problems involving the ‘right hand rule.’ The magnetism test came, so I did all the problems using my left hand instead. After the test was finished.)

Teacher: “Hey [My Name], I noticed you were using your left hand that whole test…”

Me: “Yep. I changed all my signs accordingly.”

Kid Behind Me: “You son of a b***!”
