It is a well-known medical fact that losing your eyesight significantly sharpens your remaining senses, but one customer was about to find out just how terrifyingly accurate that could be.

A woman walked into a sporting goods store looking for a birthday gift for her son. Knowing nothing about fishing, she randomly grabbed a rod and reel combo and carried it to the counter, where a clerk stood wearing dark glasses.

“Excuse me,” she said, “can you tell me if this is any good?”

“Ma’am, I’m completely blind,” the clerk smiled warmly. “But if you toss it onto the counter, I can tell you everything you need to know just from the sound.”

Skeptical, she dropped it. Clatter!

The clerk tilted his ear. “Ah. That’s a six-foot Shakespeare graphite rod, a Zebco 404 reel, and ten-pound test line. A solid, all-around setup, and lucky for you, it’s on sale for just $20.”

“Incredible!” she gasped, reaching into her purse. In her excitement, her credit card slipped out and hit the floor with a tiny flick.

“Sounds like a MasterCard,” the clerk noted smoothly.

Blushing, she bent down to retrieve it, and the sudden physical exertion caused her to accidentally let out a loud, unmistakable fart. She froze in absolute horror, but quickly rationalized—he was blind, there was no way he could look around and prove it came from her.

The clerk tapped his screen. “Alright, ma’am, your total comes to $34.50.”

“Wait,” she stammered, thoroughly confused. “Didn’t you say the rod and reel combo was only $20?”

The clerk flashed a brilliant grin.

“Yes, ma’am, the combo is $20. But the Duck Call is $11, and the Catfish Bait is $3.50.”
