The Thingy From Another World

(A young woman walks up to the counter.)

Me: “Hello, ma’am, how are you doing today?”

Customer: “Good. My husband sent me in here to get a part for his chainsaw.”

Me: “Okay. Sure I’d be glad to help you. What kind is it?”

Customer: *bewildered look* “Well, he said to just go in and tell you it’s the little metal thingy that goes in the motor and you’d know what it was.”
