Sue: Brad. How would you like to be the first subject in my science experiment?
Brad: Are you kidding? I'd be honored. But I should warn you, I can't tolerate needles or tickling.
Sue: We should be good. Okay. I'll smile at you, and then if you smile back at me, that proves my hypothesis that smiling is contagious.
Brad: Love it.
Sue: You will be subject X. The first entry in my log. Ready?
Brad: Ready. [smiles]
Sue: Brad?
Brad: Yeah?
Sue: I think you have to stop smiling. Otherwise, when I smile at you, we won't know if you smile back.
Brad: Oh, right. Of course. Okay, I'm ready. Go. [serious expression turns into a smile] Oh! Damn it, Bradley. Why can't you do this? You went to drama camp, for God sake.
