I was in a department store when I heard on the public-address system that the optical department was offering free ice cream. I headed down the escalator to take advantage of the offer, trying to decide on vanilla or chocolate. I was nearly drooling when I got to the optical section and said to the clerk, "I’m here for my ice cream."

"Ice cream?" came the reply. "Sorry. What we have is a free eye screening."
