"Does It Reach?" joke

A little boy goes fishing with his grandpa. As they are paddling round the lake,
Grandpa lights up a big cigar.
The boy looks at his Grandpa and says, "Grandpa, I sure would like to smoke one
of your big cigars."
Grandpa then asks, "Well son, will your pecker reach your anus?".
The little boy replies, "No."
"Well," says Grandpa. "Then you're too young to smoke cigars."
A little while later Grandpa pops open a beer.
The boy looks at his Grandpa and says, "Grandpa, I always wanted to drink a
beer."
Grandpa then asks, "Well son, will your pecker reach your anus?"
The little boy replies, "No."
"Well," says Grandpa. "Then you're too young to drink beer."
Soon the little boy reaches into his backpack and pulls out a big ham sandwich.
Grandpa looks at the little boy and says, "Son, I would really like to have some
of that sandwich."
The boy asks, "Grandpa, does your pecker reach your anus?"
Grandpa replies, "Why yes son, it does."
And the little boy retorts, "Well then go screw yourself. Grandma made this for
me!"
