Something went wrong. The writer asked for too much Willing Suspension of Disbelief. A character is carrying an Idiot Ball, or has suddenly become Too Dumb to Live. The series pulled out Green Rocks once too often, shilled the Creator's Pet one too many times, used a few too many Hand Waves, or unleashed a Retcon that made everyone's eyes roll out of their head. The Fourth Wall has been unintentionally and brutally broken, throwing the viewer's mind into utter chaos. Sometimes it is a force too powerful to be contained, even by willing suspension of disbelief or the MST3K Mantra. However it happened, the audience has been dealt a Wall Banger.
