Little Johnny and his grandfather have gone fishing. After a while grandpa gets thirsty and opens up his cooler for some beer. Little Johnny asks, "Grandpa can I have some beer too?"
"Can you stick your penis in your asshole?" grandpa asked back.
"No"
"Well, than your not big enough"
Granpa then takes out a cigarette and lights up. Little Johnny sees this and asks for a cigarette.
"Can you stick your penis in your asshole?" grandpa asked again.
"No"
"Well, than your not big enough"
Little Johnny gets upset and pulls out some cookies. His grandfather says, "Hey, those cookies look good, can I have some?"
Little Johnny asks, "Can you stick your penis in your asshole?"
Grandpa looks at Johnny and senses his trick so he says, "Well of course I can, I’m big enough."
Little Johnny then says, "Well, then go fuck yourself, these are my cookies"
