A woman walks into a sports equipment shop to buy a birthday present for her son—a fishing rod and reel. Not knowing which one to choose, she randomly picks one and heads toward the checkout.
Behind the counter is a clerk wearing dark sunglasses. She says, “Excuse me, sir, can you tell me about this rod and reel?”
The clerk replies, “Ma’am, I’m completely blind. But if you drop it on the counter, I can tell what it is just by the sound.”
Skeptical but curious, she drops the rod and reel onto the counter.
Without missing a beat, he says, “That’s a 6-foot Shakespeare graphite rod with a Zebco 404 reel and 10-pound test line. It’s a good all-purpose setup, and it’s on offer this week for just £20.”
Amazed, she exclaims, “That’s incredible! I’ll take it.”
As she opens her purse to get her credit card, it slips from her hand and falls to the floor.
The clerk immediately says, “Oh, that sounds like a MasterCard.”
She bends down to pick it up and, in the process, accidentally lets out a little fart. Mortified, she reassures herself: the clerk is blind—there’s no way he could possibly know it was her.
He wraps up her purchase and says, “That’ll be £31.50, please.”
Confused, she asks, “Wait, didn’t you say the rod and reel were £20? How did we get to £31.50?”
He replies calmly, “Yes, ma’am. The rod and reel are £20—and the Duck Call is £11.50.”
Without another word, she pays and rushes out of the store.
