Leonard: When's the screening?
Raj: Uh, it's tonight, but it's first-come, first-served, so we should probably get there early and wait in line.
Howard: Let's do it.
Leonard: Penny's busy with my mother, so Im in.
Sheldon: Oh, bad news. Amy's making me go shopping with her later, so looks like none of us can go.
Leonard: You do realize were allowed to have fun without you?
Howard: In fact, that's usually the trick to it.
