A man was in his front yard mowing grass, when his neighbor storms out of the house straight to the mailbox, opens it, slams it shut and storms back in.
A little later the neighbor storms out and does the exact same thing again, before storming back in even more red-faced.
As the man was getting ready to edge the lawn, out the neighbor comes again, marches to the mail box, opens it before slamming it closed harder than ever.
Puzzled by the neighbor's actions the man asked, "Is something wrong?"
"There certainly is!" the neighbor replied. "My stupid computer keeps saying, YOU'VE GOT MAIL."
