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 that it makes."

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 register, and in the meantime the woman farts.

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 ma'am, the rod and reel is $20.00, the duck call is $3.00, and the stink bait is$2.50."
