Stefan and his grandfather are fishing. Granddad pulls out a beer and the little boy says "Grandpa, can I have one of those?"

Grandpa says "Is your penis big enough to touch your asshole?" To which the little boy responds No. "Then you can't have one."

A while later, the granddad pulls out a cigar and the boy asks, "Can I have one of those?"

Grandpa says "Is your penis big enough to touch your asshole?" to which the little boy responds No. "Then you can't have one."

Later on, Grandpa and Grandson go to the grocery store for food and each buy a lottery ticket. Grandpa is unlucky, but the little boy says "I just won $50,000"

Grandpa says, "Great, your going to split that with me, right?" The little boy asks, "Grandpa, is your penis long enough to touch your asshole?" "Yes," Says grandpa.

"Then go fuck yourself!"
