OMG Please Help Urgent!! (10 pts)?

I am going to my arch enemy's pool party and I need to look hotter than her. I am 5'7 and 112lbs. I need to loose 20lbs in the next week. How??? What if I only eat 2 spoon fulls of oatmeal a day and use laxatives the whole week? Will I lose enough weight? I can't do any exercises b/c its too hard. Any information is appreciated! Thanks guys!
