When Lucy stops to help a "stranded" Henry by the side of the road.
Henry: Appreciate your time. Not everybody would have stopped like you. You're real sweet.
Lucy: Oh, yeah. Thank you.
[Henry pretends to get electrocuted while jump-starting his car]
Henry': Ha! I can't believe you fell for that!
Lucy: (sadly) Well... my grandfather died while trying to jump-start a car...
Henry: Oh... I'm so sorry. I was just joking around.
Lucy: I can't believe you fell for THAT!
