Quote from Monica in The One Where Ross Dates a Student
Monica: So, it's okay to date a student? Ross: Well, not really. I mean, technically, it's not against the rules. But it is frowned upon, especially by that professor we ran into last night: "Judgy Von Holier-than-thou." Monica: Well, Ross. You just be careful, okay? You don't want to get a reputation as "Professor McNails-his-students."
