Prompt: If one plus one equals one and a bun and two plus two equals two in a shoe, what does three plus three equal?
The riddle is a play on words. The first two equations, "one plus one equals one and a bun" and "two plus two equals two in a shoe," are nonsense. They are using the word "and" to mean "plus," but they are also using the words "bun" and "shoe" in a literal sense. This creates a contradiction, because one bun does not equal two, and two shoes do not equal four.
The third equation, "three plus three equals?" is a question. The answer to the question is not given, but the riddle implies that the answer will be nonsense, just like the first two equations.
So, the answer to the riddle is that three plus three equals nonsense. It is a play on words that is meant to be humorous.
Wrong It's six. Failed it like the rest of the party in my Dungeons and Dragons group.
