This guy is sitting outside on his lawn when he sees his blonde neighbor walk outside and check her mailbox. With a confused look on her face, she walks back inside. Five minutes later, the blonde walks outside again to check her mailbox. Seeing that there is nothing in it, she walks back inside her house. Another five minutes later, the blonde comes back outside to check her mailbox. After watching the blonde check her mailbox 3 times in a row, the guy is pretty curious. When she starts to walk back inside again, he asks, "What are you doing?"
She says, "My computer keeps telling me that I've got mail."
