One winter morning while listening to the radio, Bob and his wife hear the announcer say, "We are going to have 4-6 inches of snow today.
You must park your car on the even numbered side of the street, so the snowplow can get through."
...
Bob's wife goes out and moves her car.
A week later while they are eating breakfast, the radio announcer says, "We are expecting 6-8 inches of snow today. You must park your car on the odd numbered side of the street, so the snowplow can get through."
Bob's wife goes out and moves her car again.
The next week they are having breakfast again, when the radio announcer says, "We are expecting 8-10 inches of snow today. You must park"... then the power goes out.
Bob's wife is very upset, and with a worried look on her face she says, "Honey, I don't know what to do. Which side of the street do I need to park on so the plow can get through?"
With the love and understanding in his voice like all men who are married to blondes exhibit, Bob says, "Why don't you just leave it in the garage this time?
