Conversation with my roommate regarding my chosen profession

My Roommate: [To His Girlfriend] My mother always told me not to trust dirty whores
My Roommate's Girlfriend: So does that mean you don't trust Namby?
My Roommate: You hear that? She's calling you a dirty whore
Me: I'm not a whore, I'm going to be a lawyer!
My Roommate: What's the difference?
