One weekend afternoon a man and his grandson were fishing.
Grandpa lights up a cigarette and the little boys says "grandpa, can I have one of those?
Grandpa says " can your pee pee touch your .... hole?" The little kid looks surprised and says "no grandpa." Then grandpa says "well then your not old enough."
A little later grandpa opens up a cold beer and the little boy says "grandpa, can I have one of those?" Grandpa says " can your pee pee touch your .... hole?" The little kid says again "no grandpa." grandpa says "well then your not old enough."
A little later the kid busts out a big bag of cookies and grandpa says "hey kiddo, let me have a few of those cookies." the little kid says can your pee pee touch your .... hole? Grandpa laughs and said "of course" the little kid says "then go f@$& yourself."
