One million dollar question..

-Dad! Dad! Our teacher at school asked us to explain the difference between the word ''theoretical" and "reality".. Can you help me?
-Very well son, go and ask your mother if she would sleep with another man for one million dollars.
Kid goes and asks his mum:
-Mum...would you sleep with another man for one million dollars?
-But of-course! said the mother.
-Dad, dad! She said she would!
-Ok good, now go and ask your sister the same question...
-Jenny.. would you sleep with another man for one million dollars?
-For sure! said Jenny.
-Dad! Dad! She also said she would.
-Ok, now go ask your big brother.
-Johnny, would you sleep with another man for one million dollars?
-Well.. yeah, why not! said Johnny.
-Dad! Dad! He said yes!
And the dad goes:
-See? Theoretically we have three million dollars in this household, but in reality we have two whores and a faggot.
