A blonde quickly went out to her mailbox, look in it, closed the door and went back in the house. A few minutes later she repeated this process by checking in her mailbox again.

She did this 5 more times, and her neighbor watching her commented," you must be expecting a very important letter today the way you keep looking into your mailbox.

The blonde answered," No, I am working on my computer and it keeps telling
me that I have mail.
