Okay,Here is what a boy said :
We can agree that A girlfriend is a product of time
and money right?
Girlfriend = Time * Money
Your girlfriend is a woman!
Girfriend = Woman
Woman = Time * Money
We all know that time is money...
time = money
woman = money * money
woman = (money)^2
We also know that money is the root of all evil,
correct?
money = sqrt(evil)
woman = [sqrt(evil)]^2
Hence,
woman = evil
WOMEN ARE EVIL!!!
