Quote from Roz in When a Man Loves Two Women
Frasier: What are you doing? I can't have coffee with her. Roz: Why not? Obviously, she's still interested. Frasier: I'm seeing Cassandra, for God's sakes. I can't date two people at once. Roz: It doesn't have to be on the same night. Although, if you're good at faking a headache and you don't mind getting changed in the car... Frasier: Roz.
