You Could Look It Up

Often cited as a Thurberian catchphrase, “You could look it up” functions as a dry, slightly needling invitation to verify a claim rather than argue about it. In Thurber’s comic universe, the line also plays on the gap between confident assertion and actual knowledge: the speaker sounds authoritative while simultaneously conceding that the proof lies elsewhere. As a standalone quotation it encapsulates a skeptical, fact-checking posture—half common sense, half deadpan humor—suggesting that reality is accessible, but only if one bothers to consult the record.
