Here's a small tricky question; the kind of question to discover how we really are ourselves. Don't take this too seriously, but then again, remember that between joke and joke, truth can be found underlay!
EDIT: The offer now is one billion dollars, or whatever currency you prefer!
What wouldn't you do? What demanded task would you decline doing for those billion dollars?
As a side note, this can be even more interesting if we try not repeating what someone else says. If there's nothing you wouldn't do...just say it, then.
I'll start:
I wouldn't kill someone or something for money.
