A woman goes into a tackle shop to buy a rod and reel. She doesn't know which one to get so she just grabs one and goes over to the counter. There the assistant is standing there with dark glasses on.
She says,"Excuse me sir...can you tell me anything about this rod and reel?"
He says,"Madam I am blind but if you drop it on the counter I can tell you everything you need to know about it from the sound it makes."
She didn't believe him, but dropped it on the counter anyway.
He said," Thats a 6' graphite rod with a zebco 202 reel and 10lb test line... Its a good all round rod and reel and it's ?20.00."
She says,"Thats amazing that you can tell all that just by the sound of it dropping on the counter. I think it's what I'm looking for so i'll take it."
He walks behind the counter to the till, and in the meantine the woman farts. At first she is embarrassed but then realizes that there is no way he could tell it was her... being blind he wouldn't know that she was the only person around.
He rings up the sale and says,"That will be ?25.50." She says,"But didn't you say it was ?20.00?" He says,"Yes madam, the rod and reel is ?20.00,the duck call is ?3.00, and the catfish stink bait is ?2.50."
