Here's what you do. Ask her out, and if she says yes, take her on a picnic in a secluded place. Reach into the basket or whatever and pull out a rag. Say "That's weird. Hey, smell this. Does that smell like chloroform to you?" When she's unconscious I guess you can have your way with her, but that's not what this is about. Tha main thing is to put her in your trunk and drive to your least favorite teacher's house. Break into his basement, but make it look like you broke out. Anyway, you should have bought shackles before hand. Chain her something, strip her naked, and bruise her up. Make sure you are bruised and bloody, too. Put broken shackles on yourself(you should have bought those, too). Get out of the basement the way you came in, but make it look even more like you broke out. Run to the nearest group of people and scream "Help! I just escaped from a psychopath! He has my girlfriend in his basement! Help, call the police!" The police will show up, there will be irrefutable evidence, your dickish teacher will be removed, and the girl will view you as a hero and love you, if she doesn't remember the chloroform, that is.
