A boy goes fishing with his grandpa

The grandpa pulls a beer out of a cooler and cracks it open. The little boy said, "Grandpa, can I have a sip?"

The grandpa asked, "Well, can you reach your dick to your asshole?"

"No," said the boy.

"Well then you can't have a sip."

A few minutes go by and the grandpa lights up a cigarette. The little boy asked, "Grandpa, can I try that?"

The grandpa asked, "Can you reach your dick to your asshole?"

The boy, getting frustrated, said, "I already told you that I can't!"

"Well then you can't have any of my cigarette."

A few more minutes pass and the boy pulls a cookie out of his pocket and starts eating it. The grandpa said, "Say, can I have a bite of that?"

The boy asked, "Can you reach your dick to your asshole?"

The grandpa said, "As a matter of fact, I can!"

The boy said, "Well then go fuck yourself, grandma made these for me."
