A tayler's holiday, when they have leave to play, and cucumbers are in season. [From] cucumbers, taylers.--B. E.'s Dictionary of the Canting Crew, c. 1699
The dull session of the year; from the German phrase, "die saure gerkin-zeit," the pickled cucumber-time.--Albert Hyamson's Dictionary of English Phrases, 1922
Feast Eve of St. Boniface of Crediton,
the only saint among the five patrons of tailors whose feast day fell during summertime "cucumber season," the rest occurring from late October to mid-November. Samuel Foote's comic play Sir Jacob Jollup (1777) again associated tailors and cucumbers, referring to "a journeyman tailor -- this cross-legg'd cabbage-eating son of a cucumber." Historically, cucumbers have enjoyed a mixed reputation for culinary charm, especially in Britain. In James Boswell's Journal of a Tour to the Hebrides (1785), for example, he included this disparaging remark from Samuel Johnson: "It has been a common saying of physicians in England that a cucumber should be well sliced, and dressed with pepper and vinegar, and then thrown out, as good for nothing."
Oh, Johnson. You're such a scamp!
