A man was sitting on his porch one afternoon when he noticed that his neighbor, a blonde, went out to her mailbox, opened it, and returned to her home empty handed.
About five minutes later, he saw the blonde again. She checked the mailbox and once again, returned to her house empty handed.
She did this two more times before the man decided to ask her about it. "Why do you keep coming out to your mailbox every five minutes?" the man asked.
"Because," replied the blonde, "my computer keeps telling me that I've got mail!"
