Dr. Wilson: Why am I here?
House: Because I want to ask you about your girlfriend. I must know who she is, or you'd have told me her name.
Dr. Wilson: She doesn't have a name. It's some sort of birth defect.
House: There's only about 12 people we both know. I can't remember five of their names, so we're down to Cuddy, your ex-wives…
Dr. Wilson: Your mama.
