Girls are Evil

Proof: Girls are evil

First we state that girls require time and money: Girls = Time x Money

And we know that time is money: Time = Money

Therefore: Girls = Money x Money

And because 'money is the root of all evil': Girls = (Evil)^1/2 x (Evil)^1/2

Conclusion: Girls = Evil

Note: A problem with this proof occurred to me immediately: Since evil is negative, the square root of evil must be imaginary, which would mean that money is imaginary, and therefore, by definition, so is time. Then I realized that, in my life at least, that's pretty much true.
