Dr. Frasier Crane : I'm sorry, miss, but we are not entertaining guests this evening. You'll have to leave.
Loretta : [to Simon] Wait - you told me this was your place. You're probably not even the Duke of England.
Simon Moon : Oh, yeah? Then why do I talk this way?
Simon Moon : [to Frasier] Well, you're just a big contraceptive, aren't you?
