A woman walks into a sports shop to buy a rod and reel for her son’s birthday. She isn’t sure which one to get, so she randomly grabs a set and takes it to the counter.

The clerk, standing there in dark glasses, seems to be blind. She says, “Excuse me, sir. Can you tell me about this rod and reel?”

He responds, “Ma’am, I’m completely blind, but if you drop it on the counter, I can tell you everything about it just by the sound it makes.”

Skeptical, she drops it on the counter.

He listens for a moment and then says, “That’s a 6-foot Shakespeare graphite rod with a Zebco 404 reel and 10-pound test line. A great all-around combo, and it’s on sale this week for $20.”

Amazed, she says, “That’s incredible! I’ll take it!”

As she opens her purse to get her credit card, it slips out of her hand and falls to the floor.

“Oh, that sounds like a MasterCard,” the clerk says.

She bends down to pick up the card, and in the process, accidentally lets out a little fart. Mortified, she realizes he’s blind and figures there’s no way he could know it was her.

The man finishes ringing up the sale and says, “That’ll be $34.50, please.”

Confused, she asks, “Wait, didn’t you say the rod and reel were $20? How did you get $34.50?”

He replies, “Yes, ma’am. The rod and reel are $20, but the Duck Call is $11, and the Catfish Bait is $3.50.”

She paid the bill and left without another word.
