The Wishmonger: I don't have many rules to live by, but here is one: It's simple. Don't put anything unnecessary into yourself. No poisons or chemicals, no fumes or smoke or alcohol, no sharp objects, no inessential needles - drug or tattoo- and ... no inessential penises, either.
Karou: Inessential penises?!?! Is there any such thing as an essential one?!
The Wishmonger: When an essential one comes along you'll know. Stop squandering yourself child. Wait for love.
