Ferengi Book of Etiquette

The Ferengi Book of Etiquette was a facetious etiquette book mentioned by William T. Riker upon his, Deanna Troi and Lwaxana Troi's abduction by DaiMon Tog in 2366.

When Lwaxana protested their abduction, as Deanna and Will were Starfleet officers and the Ferengi ought to know better, Will quipped that "Tog must have missed that chapter in the Ferengi Book of Etiquette." (TNG: "Ménage à Troi")
