A blonde woman quickly went to her mailbox, looked inside, closed it, and returned to her house.
A few minutes later, she repeated the process, checking her mail again.
She did this five more times. Her watching neighbor commented, "You must be expecting a very important letter today, the way you keep looking into that mailbox."
The blonde replied, "No, I'm working on my computer, and it keeps telling me, 'You've got mail.'"
