Fishing rod

A woman goes into GigaHuge Mart to buy a rod and reel. She doesn't know which one to buy so she just grabs one and goes over to the register. There is an " associate" standing there with dark shades on. She says, " Excuse me sir, can you tell me anything about this rod and reel?" He says," Ma'am I'm blind but if you will drop it on the counter I can tell you everything you need to know about it from the sound it makes." He said," That's a 6' graphite rod with a Zebco 202 reel and 10lb. test line... it's a good all-around rod and reel and it's $20.00." She says, " that is amazing that you can tell me 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 register, and in the meantime the woman breaks wind big-time. At first she is embarrassed but then realizes 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 only $20.00?" He says, Yes ma'am, the rod and reel is $20.00, the duck call is $3.00 and the catfish stink bait is $2.50."
