With plenty of feminist readers, I can't wait to see what everyone thinks of this... Your opinions? Would it be funny if "girls" were changed to "pets" or "hobbies"?
First we state that girls require time and money.
Girls = Time + Money
And as we all know, time is money!
Time = Money
Girls = Money x Money = (Money)²
And because "Money is the root of all evil":
Money = √Evil
Girls = (√Evil)²
And we are forced to conclude:
Girls = Evil
