Change channels

A sudden, temporary change in personality, often creepy as hell, thought to be caused by demonic possession, as he/she who changes channels speaks with a deep, evil, echoing voice, and the eyes glow a deep, blood-red color while this is happening. A normally cheerful, skip though a field of flowers person suddenly says something like "I will feast on your flesh, and pick my teeth with your bones". Recently, scientists are dumping on the idea of demonic possession, and instead blaming it on severe and continuous exposure to insanity. Research has proven that this phenomena occurs at random, and with little to no provocation, and is a distant cousin to the shoop da whoop phenomenon.
