This guy was driving down the road and he sees a man hitchhiking.
He  decides to pick him up.  They are driving down the road when the
driver  notices that the hitchhiker keeps looking in a bag on his lap. 
The  driver asks: "Hey buddy, whatcha got in the bag?"  The hitchhiker
says:  "None of your fucking business."  The guy drops it and keeps
driving.   A few miles later the driver notices him looking in the bad
again and  decides to ask again.  "Hey budy, what do you have in the
bag?"  The hitchhiker says  none of your fucking business."  The guy
decides to drop it again.   A few miles later the driver notices him
looking in the bag again.   The driver says: "If you don't tell me what's
in the fucking bag, I'm going  to throw you out."  The hitchhiker says:
"None of your fucking business."   The driver locks up the brakes, opens
the door, throws the hitchhiker out  and slams on the gas.  He gets all
the way home and as he's getting out  of his car he notices the bag
sitting on the floor.  He reaches over, opens the bag and looks in it.

*(Stop right there.  Don't say anything else.  Wait for the question.)*
(So, what's in the bag!?!)*

NONE OF YOUR FUCKING BUSINESS!
