One day a lady went into a fishing shop to buy her husband a fishing pole for his birthday.

She picked up a really nice looking pole and asked the salesman how much it was. The sales man says, "I am blind but if you give me the pole I can tell how much it is by the weight."

So the lady gives him the pole and he says, "That pole is worth $45." She was amazed at how cheap that was.

So then she picked up another really nice pole, hands it to the man and he says, "This pole is worth $55." she decided that was also really cheap.

And then she picks the nicest looking pole in the place and handed it to the man and he says, "This pole is our best and it is $70." she told him that she would take it.

As she was getting the fishing pole all rung up, she had to fart really really badly. She decided since the man was blind that it really wouldn't matter if she farted in front of him so she just let it loose.

All of a sudden the man says, "It all comes up to $80."

Confused the lady says to him, "But you said the fishing pole was only $70."

He said, "It is. Its $70 for the fishing pole and $10 for the duck call."
