I have a great anti-spam system, SpamNet, installed in Outlook. It gets rid of most of the literally thousands of spam e-mails I get each month.
It also makes me sad.
I tend to leave my Outlook window up during the day, and leave the shortcut bar uncovered by other windows so I can see if I have any new mail. When new mail comes in, Spamnet flags spam and moves it to a separate folder.
So several times a day, I get to see something like this:
Inbox (6)
And then like a vacuum cleaner, quickly
Inbox (5)
Inbox (4)
Inbox (3)
Inbox (2)
Inbox
And then I have no mail.
