On a bitterly cold winter's morning a husband and wife in the North Hills of Pittsburgh 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 snowplows can get through conveniently". So the good wife went out and moved her car as instructed.  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." The good wife went out and moved her car again. 

The next week they are again having breakfast when the radio announcer says, "We are expecting 12 to 14 inches of snow today. You must park. . . . . . . . . . . . . . . . . . . . . " 
  
Then the power went off. . . . . . . .! 
  
The good wife was very upset, and with a worried look on her face she said,  "I don't know what to do.  Which side of the street do I need to park on so the snowplows can get through?" 
  
Then, with all the love and understanding in his voice those men who are  married to blondes (and those with grey hair) always exhibit, the husband replied, 
 

"Why don't you just leave the car in the garage this time?"
