It is so funny… just go through and enjoy 
Equation 1
Human = eat + sleep + work + enjoy
Donkey = eat + sleep
Therefore,
Human = Donkey + work + enjoy
if, Human – enjoy = Donkey + work
In other words,
Human that don’t know enjoy = Donkey that work (Eqn 1)
******************************************************
Equation 2
Men = eat + sleep + earn money
Donkeys = eat + sleep
Therefore,
Men = Donkeys + earn money (Eqn 2)
If Men – earn money = Donkeys
In other words,
Men that don’t earn money = Donkeys (Eqn 3)
******************************************************
Equation 3
Women = eat + sleep + spend
Donkeys = eat + sleep
Therefore, Women = Donkeys + spend (Eqn 4)
If, Women – spend = Donkeys
In other words,
Women that don’t spend = Donkeys (Eqn 5)
******************************************************
To Conclude:
>From Eqn 3 and Eqn 5
Men that don’t earn money = Women that don’t spend
So,
Men earn money not to let women become Donkeys! (Postulate 1)
Women spend not to let men become Donkeys! (Postulate 2)
>From Eqn 2 + Eqn 4, we have
Men + Women = Donkeys + earn money + Donkeys + spend
From Postulates 1 and 2, we can conclude
Man + Woman = 2 Donkeys
And the Donkeys live happily ever after!
