"Naughty or nice?"

That's not much of a choice is it? It reminds me of a Terry Pratchett quote from Witches Abroad:

"The wages of sin is death but so is the salary of virtue, and at least the evil get to go home early on Fridays."

You should do what you do based on who you are and not because you will get something out of it.  But what do I know...

For the record: I was nice. And that is all the reward I will get. There shouldn't be more than that to begin with.
