If this happened to me, I would absolutely spend a few good minutes considering the exact same thing. I seriously doubt I'd have the nerve to actually try to pull it off. But I would definitely think about it . . .
Oh, come on, ya liars. We all would. So don't give me that 'I'd return it immediately' crap.
My only question is: With all that money - why didn't they just buy the kid a new passport?
