Carl Fredricksen: [to Russell] Now, we're gonna walk to the falls quickly and quietly with no rap music or flashdancing.
Russell: Uh-huh.
Carl Fredricksen: We have three days, at best, before the helium leaks out of those balloons. And if we're not at the falls when that happens...
Russell: [behind Carl, obviously distracted, looking down] Sand.
Carl Fredricksen: ...we're not getting to the falls.
Russell: I found sand!
Carl Fredricksen: [looks up at his house, through a window, to where a picture of old Ellie hangs on the wall] Don't you worry, Ellie. We'll get our house over there.
