Chloe: I have to say, Rex, you're an idiot.
Rex: Cause I slept with her sister. I know.
Chloe: No, cause you told her about it!
Rex: What was I supposed to say? She said she'd give me another chance if I told her the truth.
Chloe: That's when you make something up. Tell her you slept with me, or the Chicago Bears team, or you were so drunk you don't remember, anything is better than telling her you slept with her sister.
