A kid and his grandpa go fishing. After a while, grandpa reaches in to his tackle box and pulls out a beer. Kid says, "Where'd you get that beer grandpa?" Grandpa says, "Grandma packed it for me." Kid says, "Can I have a swig?" Grandpa says, "I don't know, can you pull your dick between your legs and touch your own asshole with it?" Kid, very confused, says, "No, I can't." Grandpa says, "Sorry, then you can't have a swig of my beer."

Little bit more time goes by and grandpa reaches in to his tackle box and this time he pulls out a cigar. Kid says, "Where'd you get the cigar grandpa?" Grandpa says, "Grandpa packed it for me." Kid says, "Can I have a puff? Grandpa says, "I don't know, can you pull your dick between your legs and touch your own asshole with it?" Kid, still very confused, says, "No, I can't." Grandpa says, "Sorry, then you can't have a puff of my cigar."

Little bit more time goes by and this time the kid pulls a bag of chocolate chip cookies out of his tacklebox. Grandpa says, "Where'd you get those?" Kid says, "Grandma packed them for me." Grandpa says, "Can I have one?" Kid says, "I don't know, can you pull your dick between your legs and touch your own asshole with it?" Grandpa, very proud of himself, says, "Well, as a matter of fact, yes I can." Kid says, "Then you can go fuck yourself, old man, because you can't have one of my cookies."
