Mathimatical Proof that Girls are Evil

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


As we also know that "Time is Money"
Time = Money


Therefore
Girls = Money x Money = Money^2 ("^" indicates an exponent)


And since "Money is the root of all evil,"
Money = *Evil* (* = a sqaure root)


Therefore
Girls = (*Evil*)^2


And we are forced to conclude that
Girls = Evil
