My friend and I work in a lawn-mower-parts warehouse. He had the idea that his wife did not want a card on Valentine’s Day, but when he spoke to her on the phone, he discovered she was expecting one.

Not having time to buy a card on his way home, he was stuck. Then he looked at the lawn-mower trade magazines scattered around the office and got an idea.

Using scissors and glue, he created a card with pictures of mowers, next to which he wrote: “I lawn for you mower and mower each day.”
