the age old art of building a giant ball of human feces by forming multiple turds into a large sphere. This is accomplished over time and with the assistance of a refrigerator. Turd consistency must be equal to that of clay and immediate refrigation must occur in order to preserve the spherical integrity and reduce common house fly infestation

When one enters into an irregular bowel movement and produces a stool the size of a human babies arm.
Alison: “Brian, Brian….! Can you call a Paramedic. I have Limb Lump Dumped….!”

Brain: “Alison, not again. These irregular bowel movements must stop. Consider the local sewerage systems. They cannot accommodate stools such as the girth that you produce. Sewerage engineering has some advancement to make before correct distribution of your Turds can be achieved”.
