Paper Airplane

Today Cal and I were watching the Office and he got it in his head to make a paper airplane. He looked up directions, wanted more lift in his plane and proceeded to make all sorts of adjustments. Some of the buzz words he used were "drag" and "aerodynamics" and "Look Jill! I made it so it turns left!"It was very successful. One time he even got it into the sink and it still survived.

Five points if you can guess which episode it was!
