A man was trimming his bushes.
His neighbor (the blonde) walks out, checks her mail only to see that it's empty, and goes back inside.
Five minutes later, she comes back out, checks her mail again only to see that it's still empty, and goes back in.
The third time she comes out, the man asks her, "Excuse me, is there a problem?" The blonde replies, "Darn right there's a problem!
My computer keeps on telling me 'I've got mail'!"
