WWII Beans
Wikisimpsons - The Simpsons Wiki
A tin of WWII Beans, presumably meant to be eaten during World War II, was seen in the kitchen at Springfield Elementary School.
History
Lunchlady Dora used the tin when she was preparing lunch for the school's cafeteria. When Doris opened the tin, spirits came out of it and moaned eerily as they flew around the kitchen. Doris, annoyed, then told them to get into the food.
