A guy is sitting on his porch when his blonde neighbor walks out to her mailbox.

She opens the mailbox, looks in, colses it up and walks back into the house. Five minutes later, she does the same thing. After another five minutes, the same thing, but this time she's visibly angry. She comes out again after another five minutes, looking furious. She looks in the mailbox and slams it closed. As she's walking back to the house, the guy says,

"Not to be nosy, but are you expecting an important package?"

The blonde answers, "No! It's my damn computer! It keeps telling me I have mail!"
