Oo-mox for Fun and Profit

From Memory Alpha, the free Star Trek reference

Oo-mox for Fun and Profit is an instructional book on how to give oo-mox to Ferengi males. Quark recommended it to Aluura when he felt that she had not been "nice" enough to him. After reading the book, Aluura claimed the contents seemed "fun." (DS9: "Profit and Lace")
