Mathematical Proof that Girls are Evil
First we state that girls require time and money:
girls = time x money
And as we all know, "time is money"
time = money
Therefore:
girls = money x money = (money)^2
And because money is the root of all evil:
money = square root of evil
Therefore:
girls = (square root of evil) ^ 2
And we are forces to conclude that:
Girls = Evil
