Reminds me of a joke I heard;
A Carpenter walks into a local corner bar for a beer, he was told about a blind man who stops in every day, who could tell any type of wood by just smelling it.
Just then, the Blind man enters the bar.
The carpenter is so impressed about what he had heard, that he challenges the blind man to a contest.
The Blind man agrees. The rules are simple...The carpenter will lay out 5 pieces of wood on the bar, the Blind man can not touch the wood. he can only smell it before he tells everyone the type of wood that it is.
The Carpenter first lays out a piece of Red Cedar...One sniff..."Easy, Red Cedar" says the Blind man.
Then the carpenter puts down a Piece of Pine...One sniff..."Simple...Pine" says the Blind man.
Next goes down a plank of Oak...Two sniffs..."Oak" says the Blind man.
Next he lays down a piece of Ash...Three long sniffs..."Ash" says the Blind man.
Frustrated and amazed, the Carpenter walks up to a young lady sitting at the end of the bar and whispers something to her. She looks, smiles and agrees. "Shhhh" he says.
She undresses, and climbs up on the bar and lays down face up in front of the Blind man.
The Carpenter asks..."How about this one?"
The Blind man leans in...Three, Four long sniffs...But sits straight up, confused!
He asks, "Can you turn this piece over for me?"
So the young lady slowly flips over and lays down, Checks up.
"OK" says the Carpenter... "There ya go."
The Blind man leans in again and takes two long sniffs, and again straightens up, bewildered!
"I'm not quite sure on this one" The Blind man says, "The closest thing that I can come up with is....The Sh!thouse Door on a Tuna Boat!"
