This proverb warns that a houseguest, however welcome at first, outstays their charm after a short while, just as a fish begins to smell once it is a few days old. It is usually said with some humour, often by a host who feels a visit has gone on a day or two too long, or by a guest themselves who is conscious of not wanting to overstay their welcome. The comparison works because both halves of it rely on a simple, everyday fact: freshness does not last, whether in food or in company.
What’s the origin of the phrase ‘fish and guests smell after three days’?
The saying in something close to its modern English wording goes back to the Elizabethan writer John Lyly, whose prose romance Euphues and His England, published in 1580, contains the line “Fish and Guests in three days are stale.” This is the closest documented ancestor of the version familiar today, and it already combines both ideas, the fish and the overstaying guest, in a single comparison.
The phrase reached its best-known modern form through Benjamin Franklin, who gave it in his 1736 edition of Poor Richard’s almanac as “Fish and Visitors stink in 3 days.” Franklin did not coin this himself. Commentators have traced it directly back to Lyly’s earlier line, with Franklin reworking existing wording into the punchier, more memorable form that has stuck ever since.
The two images that make up the saying also have a separate history of their own. The idea that fish is only good while fresh predates the guest comparison on its own: Erasmus’s Adagia, printed in 1523, records the standalone Latin tag “Piscis nequam est, nisi recens,” meaning fish is bad unless it is fresh, already applied to friends who linger too long.
The Roman playwright Plautus is often credited as the true originator of the combined saying, but this is a misattribution. In his play Asinaria he did write separately about fish and about unwelcome guests or lovers, but he never fused the two images into the single proverb now attached to his name. The fusion belongs to Lyly, and the familiar wording belongs to Franklin, who popularised rather than invented it.
