My Paris hotel

Last week I checked into a hotel in Amsterdam and was a bit lonely. I thought, I'll call one of those girls you see advertised in phone kiosks. I picked up the phone book and found an ad for a girl calling herself Monique, a lovely girl, bending over in the photo. She had all the right curves and looked pretty.
I figured, what the heck, give her a call.
"Hello," the woman says. She sounded sexy.
Afraid I would lose my nerve if I hesitated I rushed right in."I should be straight with you. I'm in town all alone and what I really want is sex. I want it hard, I want it hot, and I want it now. We'll go hot and heavy all night; tie me up, cover me in chocolate syrup and whipped cream, anything and everything! Now, how does that sound?"
"That sounds fantastic," she says, "but you need to press 9 for an outside line sir."

How does Paris fit into that joke...?

I got the joke.

but you right about the hotel, I been there before. they have no room service.
