On the episode were marge becomes a cop ('Marge The Cop') she has to do training. One of the training excercises is to do a course in a cop car. When she finishes you can see her wearing a BLUE police shirt. Only in the next scene she walks in the house, she is wearing a WHITE, Hard Rock Cafe tee-shirt and says 'They never had my size shirt, but you get the idea', This is crazy because she was just wearing one!
