Fishin' with Grandpa

Every Sunday, Billy's Grandpa goes fishing, and after months
of begging he finally gets to go along.  On the way to the lake,
they stop off at a store.  Grandpa gets a six pack, and some
cigars.  Billy gets a box of Cracker Jacks.

   They get to the lake, and they start to fish.  Grampa smokes a
cigar and cracks open a beer.  Billy starts to eat on his Cracker
Jacks, and he gets thirsty. 

   "Jeeze, Grampa, I sure am thirsty.  Can I have a sip of that
beer?"
   "Well," says Grampa, "let me ask you a question first.  Can
your dick reach your asshole?"
   Billy is a little confused, but answers honestly and says
   "no". 

   "Then you can't have any beer," replies Grampa, and finishes
it off. 

   A little while later, Grampa smokes another cigar, and opens
another beer.  Billy eats a few more Cracker Jacks, and his thirst
worsens.
   "Man, I sure am thirsty," he says.  "Can I have a sip of your
beer?"
   Grampa looks at Billy, and asks "Can your dick reach your
asshole?"
   "No, not yet."
   "Well, then, you can't have any beer." He downs the remainder
of his beer, and tosses the can into the bottom of the boat. 

   This happens a couple more times.  Grampa always asks the same
question, and Billy always answers the same.  Pretty soon it gets
dark and Grampa decides it is time to head for home. 

   Now, Grampa isn't such a bad guy, and he decides to stop at
the store.  He gives Billy a dollar and tells him to go get
himself a soda pop.  Billy is inside for a few minutes and comes
strolling back to the car, carrying a scratch ticket. 

   Grampa is kind of disgusted at his grandson's lack of morals
and decides to tear into him.  "I give you a dollar to go buy
something to drink, and you come back with a lotto ticket.
What's going on here, son? You aren't even old enough to buy
those yet!  See if I ever give you any more money."

   Billy calmly scratches the ticket, and WOW!  he's won $10,000! 

   Grampa just doesn't know what to do. 

   "Hey," he says, "since I was nice enough to take you fishing,
and that was actually my dollar, how about you sharing that with
me?"

   Billy looks at his grandfather and says, "Let me ask you a
question.  Is your dick long enough to reach your asshole?"
   "It sure is." brags Grampa.
   "Well then, Grampa, go fuck yourself!"
