One winter morning a husband and wife in Denver were listening to the radio during breakfast. They heard the announcer say, "We are going to have 8 to 10 inches of snow today. You must park your car on the even-numbered side of the street, so the snowplows can get through."

So the good wife went out and moved her car.

A week later while they are eating breakfast again, the radio announcer said, "We are expecting 10 to 12 inches of snow today. You must park your car on the odd-numbered side of the street, so the snowplows can get through."
