A little boy goes to visit his grandparents for the weekend..

The little boy walks up to his grandpa who is outside smoking a cigar. The boy says, "Grandpa, can I have a puff of your cigar?" Grandpa says, "I don't know son, does your dick touch your asshole?" Little boy says "no". So grandpa says "then youre not old enough to smoke".

Few weeks later little boy is back at his grandparents and grandpa is outside drinking a beer. Little boy says "grandpa, can I have a sip of your beer?" Grandpa says "I don't know son, does your dick touch your asshole yet?" Little boy says "no". "Well youre not old enough to drink yet" says grandpa

So a few minutes later grandpa walks by the little boy outside eating some cookies. Grandpa asks "can I have a cookie grandson?" Little boy asks "I don't know grandpa, does your dick touch your asshole?" "Of course!" says grandpa. Little boy says "Well then you can go fuck yourself, grandma made these cookies for ME!"
