A woman goes into a shop to buy a rod and reel as a gift She doesn't know which one to get so she just grabs one and goes over to the counter where there's a shop assistant wearing dark shades. "Excuse me sir" she says "can you tell me anything about this rod and reel?" The assistant replies "Ma'am I'm 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. The assistant rings up the sale and says, "That will be $25.50." She says, "But didn't you say it was $20.00?"
