A blonde goes to her mailbox, looks inside, closes the door and goes home. A few minutes later, she comes out, goes to the mailbox, looks in, closes the door and goes home. She repeats this maneuver several times before a neighbour who was at the scene asks her:
You have to wait for a very important letter or package today!
The blonde responds: - No, it's just that this damn computer keeps telling me that I have mail!
