Sounds like a rating-grabbing stunt from the rats living inside the zombie that this series is. The series jumped the shark before I was born. It's like pancreas cancer stage 8, metaphorically speaking. I could read yaoi fanfiction written by a 14 year old girl of Sideshow Bob and Bart and get similarly funny jokes as any random episode of the Simpsons in the 21th century. But Marge's actress is getting on years and hey, Ash from Pokémon did eventually became World Champion, so maybe I will live to see the show end(I still think there is a 5 out of 10 chance of Disney making a finale movie to try to get one, last, big payoff).
