Girls= Evil

Today, during english
lesson...our english
teacher, Mrs Ang,
asked our opinions
about this following
statement...
"Money is the root of
all evil.."
My friend came out with
something but he did
not tell the teacher about it
for he's afraid it might
offend the opposite gender..
Here it is:
Girls = money x time
Since time is money,
therefore:
Girls = money x money
= (money)^2
Since money is evil..
Hence, he concluded that:
Girls = Evil...
What is your opinion
about this??
Btw, no intention to
offend here...
