"How well do you know Maths?" joke

Human = eat + sleep + work + enjoy
Pigs = eat + sleep
Hence, Human = Pigs + work + enjoy
If, Human - enjoy = Pigs + work
In other words,
Human that don't know enjoy = pigs that work
Men = eat + sleep + earn money
Pigs = eat + sleep
Hence, Men = Pigs + earn money
If Men - earn money = Pigs
In other words,
Men that don't earn money = Pigs
Women = eat + sleep + spend
Pigs = eat + sleep
Hence,
Women = Pigs + spend
If, Women - spend = Pigs
In other words,
Women that don't spend = Pigs
Summary:
Men earn money not to let women become pigs!
Women spend not to let men become pigs!
Men + Women = 2 Pigs
Wish all the pigs to be happy forever.. .. thats Maths!!!
