Is cereal soup?
Solid food in liquid, served in a bowl, eaten with a spoon. The dictionary has a definition. Both sides, a ruling, and a sentence. Below: both sides as they'd actually put it, then the ruling The Judge gives when two people bring this one into a Settle It room.
Both sides
Soup is solid food in a liquid, eaten with a spoon, from a bowl. Cereal is solid food in milk, eaten with a spoon, from a bowl. You cannot escape this.
Soup is cooked. Soup has a broth or a stock. Nobody simmers Cheerios. Cereal is cereal, the same way a salad is not a sandwich.
The Judge's ruling
Ruling: Dev's definition is a definition of 'things in a bowl.' Merriam-Webster defines soup as a liquid food, typically with a meat, fish, or vegetable stock as its base, often containing solid pieces. Stock isn't mandatory under that definition, but cereal milk is a stretch. Cole has the better argument about what people ordinarily mean by soup. Milk isn't stock, but that's not enough to win by itself. The stronger point is that we call the whole thing cereal, and the milk is there to make the cereal edible. By Dev's logic, strawberries in cream are dangerously close to soup. A court has to draw the line somewhere." Then CUT the next sentence, "A court has to stop somewhere", so the joke isn't repeated. A court has to stop somewhere.
Sentence: Dev may continue to say it at parties, but only at parties. Cole owes Dev a bowl of actual soup for the trouble.
