Re: pretty dumb question
No harleys Polly cmon girl.
OK while everyone is scratching their head on Jeffs brain buster, I submit for your consideration:
There's a prisoner in jail.
The prisoner has a visitor.
The jailkeeper, Thaard, asks the visitor: "How do you know the prisioner?"
The visitor answers..
Brothers and sisters I have none, but that person's father, is my fathers son.
How are they related?
(this is way easier than Jeff's)
