For some reason I think "Is this where you want to be when Jesus comes back?" would be funny.
Barring that, nonspecific, open-ended questions might ellicit an interesting response. "Well, are you done yet?" "Almost here?" "How many do we need?"
Or, you could take that idea and make it seem like you're up to no good, ie, "Did you dump it?" "Cover your tracks," or "Call me when you've gotten her to talk."
