Joey: Who-ah-ho.
Mr. Tribbiani: We'll go to a hotel.
Ronni: (Shrugs) We'll go to a hotel.
Joey: No you won't.
Ronni: No we won't.
Joey: If you go to a hotel you'll be...doing stuff. I want you right here where I can keep an eye on you.
Mr. Tribbiani: You're gonna keep an eye on us?
Joey: That's right, mister, and I don't care how old you are, as long as you're under my roof you're gonna live by my rules. And that means no sleeping with your girlfriend.
