Never, ever, ever, ever piss off Rihanna. And definitely don't take her money.
Rihanna showed the world (and her accountant) that the last thing you ever want to do is cross her with her explicit, dangerous, NSFW video for "Bitch Better Have My Money." After watching what she's capable of, we are certain that if we ever found ourselves borrowing money from her we would pay her what we owed her. On time. With interest.
