They weren’t catching much. after an hour or two, the grandpa pulled out a bottle of beer to enjoy.
“Grandpa, can I have some?” the boy (named Johnny) asked.
Now,the grandpa knew he couldn’t share with the boy, but he decided to crack a joke. “Johnny, can you fit your penis in your own butthole?”
“Well,” said Johnny, “no, I really don’t think I can.”
“Then no, you can’t have any beer.”
A little while later, grandpa pulled out a cigar to enjoy. Johnny immediately asked, “Grandpa, can I try?”
Again, Grandpa asked, “Can you put your penis in your own butthole?”
“No,” said Johnny dejectedly.
“Then I’m sorry – you can’t try this cigar.”
After another hour or two of not catching any fish, Johnny remembers his mommy packed him a cookie for the trip. He pulls it out and starts eating it. “Say, Johnny, how’s about givin’ your grandpy a bite of that cookie?”
Johnny asked, “Well, grandpa, can you fit your penis in your own butthole?”
Grandpa, intent on outsmarting Johnny, said, “Why of course I can!”
Johnny replied: “Good, then go fuck yourself. This is my cookie.”
