TITLE	On a Simple Method to Derive the Hairclip and Paperclip Solutions of the Curve Shortening Flow
ABSTRACT	We use a simple method to derive four important explicit graphical solutions of the curve shortening flow in the plane. From this method, one can immediately see that the hairclip and the paperclip solutions both converge to the Grim Reaper solutions as time tends to infinity.
