A little boy and his Grandpa go fishing

A little boy and his Grandfather go fishing on a quiet little lake. After a few hours of fishing the Grandfather leans forward and pulls a beer from the cooler. The little boy asks, "Grandpa can I have one of those?" When the Grandfather replies, "Can your dick touch your asshole?" When the little boy nods his head and says no the Grandfather proclaims, "Then you can't have one." An hour or so goes by and the Grandfather pulls out a cigar and lights it up only for the little boy to repeat his question. "Grandpa can I have one of those?" "Can your dick touch your asshole?" Another disappointed look and a nod of the head from the little boy to Grandfather's response "then you can't have one." When they arrive home Grandma already has dinner made and they all sit down to eat. After dinner when watching tv Grandma comes out to the living room with a full plate of cookies and explains to the little boy she made them just for him. Grandpa leans over and says, "hey can I have one of those?" The little boy asks, "can your dick touch your asshole?" The Grandfather nods his head, smiles, and says yes. To the Grandfather's surprise the little boy replies "good then go FUCK YOURSELF because Grandma made them for me!"
