With so many difficult problems to tackle (world peace, global warming, house centipedes), why not take care of the ones you can? For example: when your girlfriend says, "Fuck my asshole, please" one should gladly accommodate.
It is a simple demand, after all, and with an asshole as lovely as this lady has, it becomes quite a privilege. And though you may not be winning any Nobel prizes for fucking an ass, 'tis a noble pursuit nonetheless.
