Proof: Girls are the root of all evil.

if girls require time _and_ money, should that be stated


Girls = Time + Money


instead? This leaves us with, using the well-known fact that time is money
which you mentioned,


Girls = 2*Money


Under the assumption that money is the root of all evil, it can now be found
that


Girls = 2*sqrt(evil)


In words, girls are _twice_ the root of all evil, instead of just evil,as you
proved.
