Great tongue-in-cheek piece from two years ago by Ben Pobjie:
I have prepared, for the benefit of my fellow man and also people who play football, a Handy Guide To Not Raping People. Feel free to print it out and keep it in your shirt pocket, men, so next time you find yourself in an awkward situation where it seems you have no choice but to rape someone, you can check the guide and gracefully extricate yourself from the sticky predicament.
