It’s All In Your Head

(I’m a cashier at the local grocery store. One evening, a customer comes up to my till.)

Me: “Did you find everything okay today, sir?”

Customer: “Yes, thank you, I did.”

(I start scanning his items. Out of nowhere, he grabs the hand-held scanner and points it at his forehead. Naturally, nothing comes up.)

Customer: “Just as I thought. I’m priceless!”
