This one has been floating around the net for a while but i thought i might share it here.
Proof that girls are evil:
firstly, lets start with an equation that we all know is true, girls take time and money. and the more time you spend with them, the more money you have to spend too, therefore:
girls = money * time
In the modern age world, everyone knows that times equals money:
time = money
Therefore:
girls = money * money
And another well know fact is money is the root of all evil, therefore...
Girls = Evil
