One winter morning at breakfast a couple was listening to the radio. They heard the announcer say, “We are going to have 8-10 inches of snow today. You must park your car on the even-numbered side of the street, so the snowplow can get through.” The wife went out and moved her car.
A week later while they are eating breakfast, the radio announcer said, “We are expecting 10-12 inches of snow today, you will need to move your car to the odd-numbered side of the street so the snowplow can get through.” So the wife went out and moved her car again.
The next week, while they were eating breakfast, the radio announcer said, “We are expecting 12-14 inches of snow today and you must park…” Then the power went off! The wife was very upset. With a worried look on her face she said, “Honey, I don’t know what to do. Which side of the street am I supposed to park on?”
