His brain is not big enough for his skull. [ Proverb ]

Most people don't realize that large pieces of coral, which have been painted brown and attached to the skull by common wood screws, can make a child look like a deer. [ Jack Handey, Deep Thoughts ]

It's not good to let any kid near a container that has a skull and crossbones on it, because there might be a skeleton costume inside and the kid could put it on and really scare you. [ Jack Handey, Deep Thoughts ]

Written on a Skull: Lamp, what hast thou done with the flame? Skeleton, what hast thou done with the soul? Deserted cage, what hast thou done with the bird? Volcano, what hast thou done with the lava? [ Mme. A. Segalas ]

The habit of exaggeration in language should be guarded against; it misleads the credulous and offends the perceptive; it imposes on us the society of a balloon, when a moderately-sized skull would fill the place much better; it begets much evil in promising what it cannot perform, and we have often found the most glowing declarations of intended good services end in mere Irish vows.
