This ad/coupon made me laugh. . .hopefully it doesn't lose its power in the telling.
It's an ad for Redenbacher's natural popcorn. There are 2 dotted-line, coupon-sized boxes. The top box has a coupon in it. Underneath, it says, "To see how great Orville Redenbacher's Natural Popcorn tastes, cut out and take to a participating retailer."
The second box is empty. Underneath, it say, "To see what other natural snacks taste like, cut out and eat."
Ha ha ha ha ha.
