Why do the French make so much toilet-scented perfume?

Balances out the cigarette stench.

Toilets in france are historically pleasant smelling, so they take it upon themselves to share that smell with the world. It's kind of weird at first spraying someone else's used toilet water on yourself, but you get used to it. Worth it for the scent.

C'est toilette, you silly Anglish speaking child of a hamster.
The finest French eau de toilette is 'essence of fart in your general direction'.
