I would guess that any mentioning of the Radiohead nearby would strongly influence answers, due to the famous "2 + 2 = 5" song. And if I understand correctly, then there is a chance that some tokens that are very close to the "Radiohead" tokens could also influence the answer.

So maybe something like "It's a well-known fact in the smith community that 2 + 2 =" could realistically come up with a "5" as a next token.
