Using money, I will show that women are evil.
First, we know that women use time and money. So:
Women = Time * Money
We also know that time is money, so:
Women = Money * Money
Women = Money2
We know that Money is the root of all Evil, so the square root of Evil equals Money.
Women = (sqrt(Evil))2
Women = Evil
...I don't believe this, in case you were wondering, but since we're talking about both the ladies and money, I thought it was perfect.
