A blind man applies for a job at a saw mill.

The owner interviewing him asks him what kind of a job he is interested in. The blind man says "Inspecting wood."
The owner laughs and says "But you're blind!"

The blind man replies, "Test me! I can sniff any wood and tell you what it is."

The owner agrees, and gives him a piece of wood to smell, "Tell me what kind of wood this is."

The blind man plainly replies "It's pine."

The owner looking surprised grabs another piece and sticks it under the blind mans nose. The blind man says it is mahogany.

The owner thinks for a bit, then says, "I have one more piece for you to smell."

He gets his secretary to sit spread-eagle on his desk and he asks the blind man what kind it is, pushing his head toward the secretary's crotch.

The blind man replies, "Wwwhheeeeewwwwww wwwwweeeeeee!
That's the shit-house door off of a tuna trawler!"
