A cucumber should be well sliced, and dressed with pepper and vinegar, and then thrown out, as good for nothing.

-Johnson, Samuel known as Dr Johnson
  Remark, 5 Oct. Quoted in  James Boswell  The Journal of a Tour to the Hebrides (1785).

You are offered a piece of bread and butter that feels like a damp handkerchiefand sometimes, when cucumber is added to it, like a wet one.

-MacKenzie, Sir (Edward Montague) Compton
  Vestal Fire, bk.1, ch.3.

Where the satyrs are chattering, nymphs with their flattering Glimpse of the forest enhance All the beauty of marrow and cucumber narrow And Ceres will join in the dance.

-Sitwell, Dame Edith Louisa
