This is Dave and Shaun. Dave has the beard.

In trigonometry we have the Law of Sines. This law says that in any triangle the ratio of the length of side A to the sine of the angle A is equal to the ratio of the length of side B to the sine of the angle B.

In herbology, they have the Law of Signs. This law says that what you see is what you get. One can tell that broccoli is good for the nervous system because broccoli looks like a brain. Beets announce their benefits for the circulatory system with their blood red color. Cheeseweed, found growing up in cracks of sidewalks, is good for breaking up kidney stones.

David follows the Law of Auditory Signs.

The magnanimity of his soul manifests in the mellifluousness of his voice.
