I enjoy screwing with powerful people as much as the next person, but I kinda draw the line at taking something that doesn't belong to me (whether it's as a gift to others or not). If you find a quarter in phone, that's different--somebody left it there, it's there for the taking. I don't know, I guess it's just the whole karma thing. If I steal a newspaper, somebody will steal the stereo out of my car. Maybe it's just how I've trained myself, but it certainly keeps me out of trouble.
