A cooked chicken appeared as a hallucination.
History[]
After Marge drunk some tap water and hallucinated the walls melting again (which was heavily implied to be the result of Shelbyville spiking the water supply of Springfield as revenge for the latter torching their city hall), the chicken, in a british accent, popped out of the oven and declared that he personally thought he was overdone before flying off with red colored waves emitting from it.
