Little Johnny sees his grandpa smoking a cigar.

"Grandpa! What is that? Can I try?"

"I dunno Little Johnny... Can your dick touch your asshole?"

"....um not yet."

"Then you can't. Maybe when you're older."

*Little Johnny walks away disappointedly*

*a few days later, Grandpa is drinking a beer and Little Johnny walks by and notices*

"Grandpa! What is that!? Can I try some?"

"I dunno Little Johnny... Can your dick touch your asshole yet?"

"....no."

"Then you can't, maybe when you're older."

*Little Johnny walks away mad*

*Couple days later Little Johnny is sitting at the table eating a plate of chocolate chip cookies and Grandpa comes walking by and notices*

"Ohhhh chocolate chip! Can I have a cookie Johnny?"

"I dunno Grandpa, can your dick touch your asshole?"

"It sure can!"

"Then go fuck yourself Grandpa these cookies are mine!"
