So I finally thought of something to write here. I'm sure a lot of people have heard the following proof that girls are evil:

First we state that girls require time and money.

Girls = Time * Money

And as we all know, time is money.

Time = Money

Therefore:

Girls = Money * Money = Money ²

And because money is the root of all evil:

Money = Evil ^1/2

Therefore:

Girls = (Evil ^1/2)²

And we are forced to conclude that:

Girls = Evil

Well I want to prove that money is imaginary.

We know that money is the root of all evil:

Money = Evil ^1/2

And I doubt anyone would disagree that evil is negative:

Evil < 0

We know that the square root of a negative number is imaginary:

(-1)^1/2 = i

And so money is imaginary:

Money = i * ( | Evil | )^1/2
