Get the cranial rectal proximity syndrome mug.
Cranial-Rectal Entanglement Syndrome (also known as Anal-Cranial Entanglement Syndrome, or ACES) is a disorder which is characterized by someone who is incapable of performing a simple task due to pure stupidity or an apparent misplacement and, therefore, disuse of their cerebellum and cerebrum.

Esp. applies when someone has one job and cannot complete it properly, if at all.
Karen suffers from such a severe case of Cranial-Rectal Entanglement Syndrome, she has a visible tan-line around her neck.

I’ve run into a catch-22 due to two of the people I rely on having ACES.

Get the Rectal Cranial Intrusion mug.
A condition wherein the patient's rectum is blocked (impacted) by their own cranial matter, resulting in the following symptoms: inability to think critically, difficulty processing rational arguments, loss of desire to collaborate. Oddly it does not impact the ability to pass flatus.

Those suffering from this condition also often suffer from procto-milontas.
Nurse - the patient is clearly suffering from a cranial-rectal impaction (syndrome). Please provide 30 mg of Thorazine and be prepared to perform an attitute adjustment.
