Lacking Self Awareness

I won this at the 'Guess Your Weight Challenge'. I figured since I weigh a bit more than I look then it would be a lock for the prize. I figured that I look about 230 and weigh about 250 giving me a nice 20 pound cushion. Anyway, the guy guessed 272 and I figured he was kidding and was just conceding the prize to me. I jumped on the scale and to my horror the needle flew past 250, 260, 270 and settled on 268.5 pounds. I had no idea that my shoes weighed 10 pounds each! So I won the prize and have vowed to get new shoes when I get home. Sarah said get new shoes and NutriSystem.
