Somehow it came about that Emily decided she could jump up and down, while holding onto the arm of a chair, for a full hour.
My father-in-law started timing it for her.
Emily: What'll you give me if I do it?
Phil: I'll give you all the money I have in this pocket.
Emily: I'll bet you don't even have any money in that pocket.
Phil: Maybe I have a hundred dollar bill!
At the six minute mark, Emily groaned and collapsed.
Phil: I suppose I get to keep my hundred dollars.
Emily: I suppose you can't even show me those hundred dollars!
She's currently trying again.
