I cannot figure out the smiley face puzzle. Please help!?

I don't know if you already figured it out or not, but here is the solution. The upper left is the square with the knob. The knob faces the left side. To the right of that is the Tetris type shape that is like a little pyramid. The base of it is vertical with the top above the right eye of the Smiley face. To the right of that is the zigzag shape. It is turned so it fills in above the top of the pyramid and makes up the upper right corner of the Smiley face. Just below that is the you shaped piece and it is wrapped around the right corner of the mouth. To the left filling on thenose area is the other block with the knob. The knob is facing to the left. Next below the right eye is the L piece. It is under the right eye and wraps around the left side of the eye as well. Just below that is the other zigzag piece to make up the lower left corner of the face. Finally the straight rod is the right side base of the face.
