    A Proof That 2 = 1

     X = Y                  Given
     X^2 = XY               Multiply both sides by X
     X^2 - Y^2 = XY - Y^2   Subtract Y^2 from both sides
     (X+Y)(X-Y) = Y(X-Y)    Factor both sides
     (X+Y) = Y              Cancel out common factors
     Y+Y = Y                Substitute in from line 1
     2Y = Y                 Collect the Y's
     2 = 1                  Divide both sides by Y

      A classic :) It must have been 7 or 8 years since I last saw it, I'm sure that its much much older. Took me a while to figure out. --- Arguing on the internet is like running in the Special Olympics. Even if you win, you're still retarded.
