[flashback to Lily in the school cafeteria:]
Scooter: Hey, Lily. I saw you have seventh period free. So do I. You want to run away together?
Lily: Let me be clear, Scooter, there's no way you and I can ever be together. [Scooter stares longingly into her eyes] Right now.
Scooter: I'll see you tomorrow, Lily. It's Tijuana Tuesday.
[present:]
Marshall: "Right now"? You "right nowed" Scooter? You need to let Scooter off the hook once and for all.
Lily: You're right. Day after tomorrow, that's exactly what I'm gonna do.
Marshall: Why not tomorrow?
Lily: Baby, I can't ruin Tijuana Tuesday.
