The snowplough
 

Michael and his wife live in Minnesota. One winter morning while listening to the radio, they hear 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 snowplow can get through.”
Michael’s wife goes out and moves her car.

A week later, while having breakfast, they hear the radio announcer saying again: “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 snowplow can get through.”
So, Michael’s wife goes out and moves her car as requested.

The next week they were having breakfast again, when the radio announcer said: “We are expecting 12 to 14 inches of snow today. You must park……”
But then the electric power went out.

Michael’s wife got very upset and, with a worried look on her face, she asked: "Honey, what am I going to do? Which side of the street should I park now, so the plow can get through?"

With understanding in his voice, Michael said:
"Why don’t you just leave it in the garage this time?"
