Erin: So, if you were to jump up and down on the spot for an hour straight you'd burn 500 calories.
Mary: How much weight is that?
Erin: So, there is six hours until the reunion starts, you'll need an hour or so to get ready...
Aunt Sarah: An hour? That wean's not well.
Erin: ..which leaves... five hours? So, 500 calories by five hours...
Mary: Is how much weight?
Erin: 500 times five...
Orla: What are we doing, Erin?
Mary: Cut to the chase, girls! How many pounds can we lose?
Erin: Almost one.
Mary: Almost one?! Is that it? Are you sure?
Orla: The numbers never lie, Aunt Mary.
