One day a boy is with his grandpa and his grandpa is drinking an ice cold beer and the boy asks
"that looks good grandpa, can i have some?"
and the grandpa replies
"can your dick touch your asshole?"
"No"
"when it can you can have some beer"
so later the granpa lights up a cigar and puffs it and the boy says
"that looks good grandpa, can i try?'
"can you touch your dick to your asshole?"
"No"
"then you cant try it"
shortly after the boy leaves and comes back with some freshly baked warm cookies and starts to eat them when the grandpa asks
"those look good, can i have one?"
the boy says
"can you touch your dick to your asshole?"
"yes"
"well then, go fuck yourself, cause grandma made these for me"
