A boy came home from school one day and went up to Dad. "Pop, I've gotta
write a paper on the difference between theory and fact. Can you help me?"
"Why sure son. Go and ask your mom if she would sleep with old Mr. Johnson
next door for half-a-million dollars." The son was puzzled at this, but went
and asked mom anyway. He walked back in the room a short time later and said
"Yeah, mom would do that." "Go and ask your sister the same question." said
the father. Junior ran up the stairs, asked Sis, and came thundering down
the stairs. "She said she would also." "Okay son, here's the difference: In
theory, we're millionaires. But, in fact, we're living with a couple of
sluts."
